Function linear_polar

Source 
pub fn linear_polar(
    src: &impl ToInputArray,
    dst: &mut impl ToOutputArray,
    center: Point2f,
    max_radius: f64,
    flags: i32,

👎Deprecated: This function produces same result as cv::warpPolar(src, dst, src.size(), center, maxRadius, flags)
Expand description

Remaps an image to polar coordinates space.

Deprecated: This function produces same result as cv::warpPolar(src, dst, src.size(), center, maxRadius, flags)

@internal Transform the source image using the following transformation (See [polar_remaps_reference_image] “Polar remaps reference image c)”): block formula

where block formula

and block formula

§Parameters

  • src: Source image
  • dst: Destination image. It will have same size and type as src.
  • center: The transformation center;
  • maxRadius: The radius of the bounding circle to transform. It determines the inverse magnitude scale parameter too.
  • flags: A combination of interpolation methods, see [interpolation_flags]

Note:

  • The function can not operate in-place.
  • To calculate magnitude and angle in degrees [cart_to_polar] is used internally thus angles are measured from 0 to 360 with accuracy about 0.3 degrees.
