//! # Image Processing
//!
//! This module includes image-processing functions.
//! # Image Filtering
//!
//! Functions and classes described in this section are used to perform various linear or non-linear
//! filtering operations on 2D images (represented as Mat's). It means that for each pixel location
//!  in the source image (normally, rectangular), its neighborhood is considered and used to
//! compute the response. In case of a linear filter, it is a weighted sum of pixel values. In case of
//! morphological operations, it is the minimum or maximum values, and so on. The computed response is
//! stored in the destination image at the same location . It means that the output image
//! will be of the same size as the input image. Normally, the functions support multi-channel arrays,
//! in which case every channel is processed independently. Therefore, the output image will also have
//! the same number of channels as the input one.
//!
//! Another common feature of the functions and classes described in this section is that, unlike
//! simple arithmetic functions, they need to extrapolate values of some non-existing pixels. For
//! example, if you want to smooth an image using a Gaussian  filter, then, when
//! processing the left-most pixels in each row, you need pixels to the left of them, that is, outside
//! of the image. You can let these pixels be the same as the left-most image pixels ("replicated
//! border" extrapolation method), or assume that all the non-existing pixels are zeros ("constant
//! border" extrapolation method), and so on. OpenCV enables you to specify the extrapolation method.
//! For details, see [border_types]
//!
//! @anchor filter_depths
//! ### Depth combinations
//! Input depth (src.depth()) | Output depth (ddepth)
//! --------------------------|----------------------
//! CV_8U | -1/CV_16S/CV_32F/CV_64F
//! CV_16U/CV_16S | -1/CV_32F/CV_64F
//! CV_32F | -1/CV_32F
//! CV_64F | -1/CV_64F
//!
//!
//! Note: when ddepth=-1, the output image will have the same depth as the source.
//!
//!
//! Note: if you need double floating-point accuracy and using single floating-point input data
//! (CV_32F input and CV_64F output depth combination), you can use [Mat].convertTo to convert
//! the input data to the desired precision.
//!
//! # Geometric Image Transformations
//!
//! The functions in this section perform various geometrical transformations of 2D images. They do not
//! change the image content but deform the pixel grid and map this deformed grid to the destination
//! image. In fact, to avoid sampling artifacts, the mapping is done in the reverse order, from
//! destination to the source. That is, for each pixel  of the destination image, the
//! functions compute coordinates of the corresponding "donor" pixel in the source image and copy the
//! pixel value:
//!
//! 
//!
//! In case when you specify the forward mapping , the OpenCV functions first compute the corresponding inverse mapping
//!  and then use the above formula.
//!
//! The actual implementations of the geometrical transformations, from the most generic remap and to
//! the simplest and the fastest resize, need to solve two main problems with the above formula:
//!
//! - Extrapolation of non-existing pixels. Similarly to the filtering functions described in the
//! previous section, for some , either one of , or , or both
//! of them may fall outside of the image. In this case, an extrapolation method needs to be used.
//! OpenCV provides the same selection of extrapolation methods as in the filtering functions. In
//! addition, it provides the method #BORDER_TRANSPARENT. This means that the corresponding pixels in
//! the destination image will not be modified at all.
//!
//! - Interpolation of pixel values. Usually  and  are floating-point
//! numbers. This means that  can be either an affine or perspective
//! transformation, or radial lens distortion correction, and so on. So, a pixel value at fractional
//! coordinates needs to be retrieved. In the simplest case, the coordinates can be just rounded to the
//! nearest integer coordinates and the corresponding pixel can be used. This is called a
//! nearest-neighbor interpolation. However, a better result can be achieved by using more
//! sophisticated [interpolation methods](http://en.wikipedia.org/wiki/Multivariate_interpolation) ,
//! where a polynomial function is fit into some neighborhood of the computed pixel , and then the value of the polynomial at  is taken as the
//! interpolated pixel value. In OpenCV, you can choose between several interpolation methods. See
//! [resize] for details.
//!
//!
//! Note: The geometrical transformations do not work with `CV_8S` or `CV_32S` images.
//!
//! # Miscellaneous Image Transformations
//! # Drawing Functions
//!
//! Drawing functions work with matrices/images of arbitrary depth. The boundaries of the shapes can be
//! rendered with antialiasing (implemented only for 8-bit images for now). All the functions include
//! the parameter color that uses an RGB value (that may be constructed with the Scalar constructor )
//! for color images and brightness for grayscale images. For color images, the channel ordering is
//! normally *Blue, Green, Red*. This is what imshow, imread, and imwrite expect. So, if you form a
//! color using the Scalar constructor, it should look like:
//!
//! 
//!
//! If you are using your own image rendering and I/O functions, you can use any channel ordering. The
//! drawing functions process each channel independently and do not depend on the channel order or even
//! on the used color space. The whole image can be converted from BGR to RGB or to a different color
//! space using cvtColor .
//!
//! If a drawn figure is partially or completely outside the image, the drawing functions clip it. Also,
//! many drawing functions can handle pixel coordinates specified with sub-pixel accuracy. This means
//! that the coordinates can be passed as fixed-point numbers encoded as integers. The number of
//! fractional bits is specified by the shift parameter and the real point coordinates are calculated as
//!  . This feature is
//! especially effective when rendering antialiased shapes.
//!
//!
//! Note: The functions do not support alpha-transparency when the target image is 4-channel. In this
//! case, the color[3] is simply copied to the repainted pixels. Thus, if you want to paint
//! semi-transparent shapes, you can paint them in a separate buffer and then blend it with the main
//! image.
//!
//! # Color Space Conversions
//! # ColorMaps in OpenCV
//!
//! The human perception isn't built for observing fine changes in grayscale images. Human eyes are more
//! sensitive to observing changes between colors, so you often need to recolor your grayscale images to
//! get a clue about them. OpenCV now comes with various colormaps to enhance the visualization in your
//! computer vision application.
//!
//! In OpenCV you only need applyColorMap to apply a colormap on a given image. The following sample
//! code reads the path to an image from command line, applies a Jet colormap on it and shows the
//! result:
//!
//! @include snippets/imgproc_applyColorMap.cpp
//! ## See also
//! [colormap_types]
//!
//! # Planar Subdivision
//!
//! The Subdiv2D class described in this section is used to perform various planar subdivision on
//! a set of 2D points (represented as vector of Point2f). OpenCV subdivides a plane into triangles
//! using the Delaunay's algorithm, which corresponds to the dual graph of the Voronoi diagram.
//! In the figure below, the Delaunay's triangulation is marked with black lines and the Voronoi
//! diagram with red lines.
//!
//! 
//!
//! The subdivisions can be used for the 3D piece-wise transformation of a plane, morphing, fast
//! location of points on the plane, building special graphs (such as NNG,RNG), and so forth.

/// statistics, the function computes probability of each element value in respect with the empirical
/// probability distribution represented by the histogram. See how, for example, you can find and track
/// a bright-colored object in a scene:
///
/// - Before tracking, show the object to the camera so that it covers almost the whole frame.
/// Calculate a hue histogram. The histogram may have strong maximums, corresponding to the dominant
/// colors in the object.
///
/// - When tracking, calculate a back projection of a hue plane of each input video frame using that
/// pre-computed histogram. Threshold the back projection to suppress weak colors. It may also make
/// sense to suppress pixels with non-sufficient color saturation and too dark or too bright pixels.
///
/// - Find connected components in the resulting picture and choose, for example, the largest

/// The function draws contour outlines in the image if  or fills the area
/// bounded by the contours if  . The example below shows how to retrieve
/// connected components from the binary image and label them: :
/// @include snippets/imgproc_drawContours.cpp
///
/// ## Parameters
/// * image: Destination image.
/// * contours: All the input contours. Each contour is stored as a point vector.
/// * contourIdx: Parameter indicating a contour to draw. If it is negative, all the contours are drawn.
/// * color: Color of the contours.
/// * thickness: Thickness of lines the contours are drawn with. If it is negative (for example,
/// thickness=[FILLED] ), the contour interiors are drawn.
/// * lineType: Line connectivity. See [line_types]
/// * hierarchy: Optional information about hierarchy. It is only needed if you want to draw only
/// some of the contours (see maxLevel ).
/// * maxLevel: Maximal level for drawn contours. If it is 0, only the specified contour is drawn.
/// If it is 1, the function draws the contour(s) and all the nested contours. If it is 2, the function
/// draws the contours, all the nested contours, all the nested-to-nested contours, and so on. This
/// parameter is only taken into account when there is hierarchy available.
/// * offset: Optional contour shift parameter. Shift all the drawn contours by the specified
///  .
///
/// Note: When thickness=#FILLED, the function is designed to handle connected components with holes correctly
/// even when no hierarchy data is provided. This is done by analyzing all the outlines together
/// using even-odd rule. This may give incorrect results if you have a joint collection of separately retrieved
/// contours. In order to solve this problem, you need to call [draw_contours] separately for each sub-group
/// of contours, or iterate over the collection using contourIdx parameter.
///
/// ## C++ default parameters
/// * thickness: 1
/// * line_type: LINE_8
/// * hierarchy: noArray()
/// * max_level: INT_MAX
/// * offset: Point()

///
/// ## Parameters
/// * image: Input/output 1- or 3-channel, 8-bit, or floating-point image. It is modified by the
/// function unless the [FLOODFILL_MASK_ONLY] flag is set in the second variant of the function. See
/// the details below.
/// * mask: Operation mask that should be a single-channel 8-bit image, 2 pixels wider and 2 pixels
/// taller than image. If an empty Mat is passed it will be created automatically. Since this is both an
/// input and output parameter, you must take responsibility of initializing it.
/// Flood-filling cannot go across non-zero pixels in the input mask. For example,
/// an edge detector output can be used as a mask to stop filling at edges. On output, pixels in the
/// mask corresponding to filled pixels in the image are set to 1 or to the specified value in flags
/// as described below. Additionally, the function fills the border of the mask with ones to simplify
/// internal processing. It is therefore possible to use the same mask in multiple calls to the function
/// to make sure the filled areas do not overlap.
/// * seedPoint: Starting point.
/// * newVal: New value of the repainted domain pixels.
/// * loDiff: Maximal lower brightness/color difference between the currently observed pixel and
/// one of its neighbors belonging to the component, or a seed pixel being added to the component.
/// * upDiff: Maximal upper brightness/color difference between the currently observed pixel and
/// one of its neighbors belonging to the component, or a seed pixel being added to the component.
/// * rect: Optional output parameter set by the function to the minimum bounding rectangle of the
/// repainted domain.
/// * flags: Operation flags. The first 8 bits contain a connectivity value. The default value of
/// 4 means that only the four nearest neighbor pixels (those that share an edge) are considered. A
/// connectivity value of 8 means that the eight nearest neighbor pixels (those that share a corner)
/// will be considered. The next 8 bits (8-16) contain a value between 1 and 255 with which to fill
/// the mask (the default value is 1). For example, 4 | ( 255 \<\< 8 ) will consider 4 nearest
/// neighbours and fill the mask with a value of 255. The following additional options occupy higher
/// bits and therefore may be further combined with the connectivity and mask fill values using
/// bit-wise or (|), see #FloodFillFlags.
///
///
/// Note: Since the mask is larger than the filled image, a pixel  in image corresponds to the
/// pixel  in the mask .

///
/// - in case of a grayscale image and floating range

///
///
/// - in case of a grayscale image and fixed range

///
///

/// 
///
///
/// - in case of a color image and fixed range
/// 
/// 
/// and
/// 
///
///
/// where  is the value of one of pixel neighbors that is already known to belong to the
/// component. That is, to be added to the connected component, a color/brightness of the pixel should
/// be close enough to:
/// - Color/brightness of one of its neighbors that already belong to the connected component in case
/// of a floating range.
/// - Color/brightness of the seed point in case of a fixed range.
///
/// Use these functions to either mark a connected component with the specified color in-place, or build
/// a mask and then extract the contour, or copy the region to another image, and so on.
///
/// ## Parameters
/// * image: Input/output 1- or 3-channel, 8-bit, or floating-point image. It is modified by the
/// function unless the [FLOODFILL_MASK_ONLY] flag is set in the second variant of the function. See
/// the details below.
/// * mask: Operation mask that should be a single-channel 8-bit image, 2 pixels wider and 2 pixels
/// taller than image. If an empty Mat is passed it will be created automatically. Since this is both an
/// input and output parameter, you must take responsibility of initializing it.
/// Flood-filling cannot go across non-zero pixels in the input mask. For example,
/// an edge detector output can be used as a mask to stop filling at edges. On output, pixels in the
/// mask corresponding to filled pixels in the image are set to 1 or to the specified value in flags
/// as described below. Additionally, the function fills the border of the mask with ones to simplify
/// internal processing. It is therefore possible to use the same mask in multiple calls to the function
/// to make sure the filled areas do not overlap.
/// * seedPoint: Starting point.
/// * newVal: New value of the repainted domain pixels.
/// * loDiff: Maximal lower brightness/color difference between the currently observed pixel and
/// one of its neighbors belonging to the component, or a seed pixel being added to the component.
/// * upDiff: Maximal upper brightness/color difference between the currently observed pixel and
/// one of its neighbors belonging to the component, or a seed pixel being added to the component.
/// * rect: Optional output parameter set by the function to the minimum bounding rectangle of the
/// repainted domain.
/// * flags: Operation flags. The first 8 bits contain a connectivity value. The default value of
/// 4 means that only the four nearest neighbor pixels (those that share an edge) are considered. A
/// connectivity value of 8 means that the eight nearest neighbor pixels (those that share a corner)
/// will be considered. The next 8 bits (8-16) contain a value between 1 and 255 with which to fill
/// the mask (the default value is 1). For example, 4 | ( 255 \<\< 8 ) will consider 4 nearest
/// neighbours and fill the mask with a value of 255. The following additional options occupy higher
/// bits and therefore may be further combined with the connectivity and mask fill values using
/// bit-wise or (|), see #FloodFillFlags.
///
///
/// Note: Since the mask is larger than the filled image, a pixel  in image corresponds to the
/// pixel  in the mask .

///
/// Before passing the image to the function, you have to roughly outline the desired regions in the
/// image markers with positive (\>0) indices. So, every region is represented as one or more connected
/// components with the pixel values 1, 2, 3, and so on. Such markers can be retrieved from a binary
/// mask using [find_contours] and [draw_contours] (see the watershed.cpp demo). The markers are "seeds" of
/// the future image regions. All the other pixels in markers , whose relation to the outlined regions
/// is not known and should be defined by the algorithm, should be set to 0's. In the function output,
/// each pixel in markers is set to a value of the "seed" components or to -1 at boundaries between the
/// regions.
///
///
/// Note: Any two neighbor connected components are not necessarily separated by a watershed boundary
/// (-1's pixels); for example, they can touch each other in the initial marker image passed to the
/// function.
///
/// ## Parameters
/// * image: Input 8-bit 3-channel image.
/// * markers: Input/output 32-bit single-channel image (map) of markers. It should have the same
