Struct opencv::dnn::Image2BlobParams

#[repr(C)]
pub struct Image2BlobParams {
    pub scalefactor: Scalar,
    pub size: Size,
    pub mean: Scalar,
    pub swap_rb: bool,
    pub ddepth: i32,
    pub datalayout: DataLayout,
    pub paddingmode: ImagePaddingMode,
}

Processing params of image to blob.

It includes all possible image processing operations and corresponding parameters.

Note: The order and usage of scalefactor and mean are (input - mean) * scalefactor. The order and usage of scalefactor, size, mean, swapRB, and ddepth are consistent with the function of [blobFromImage].

Fields

scalefactor: Scalar

scalefactor multiplier for input image values.

size: Size

Spatial size for output image.

mean: Scalar

Scalar with mean values which are subtracted from channels.

swap_rb: bool

Flag which indicates that swap first and last channels

ddepth: i32

Depth of output blob. Choose CV_32F or CV_8U.

datalayout: DataLayout

Order of output dimensions. Choose DNN_LAYOUT_NCHW or DNN_LAYOUT_NHWC.

paddingmode: ImagePaddingMode

Image padding mode. see also: ImagePaddingMode.

Implementations

impl Image2BlobParams

pub fn default() -> Result<Image2BlobParams>

pub fn new( scalefactor: Scalar, size: Size, mean: Scalar, swap_rb: bool, ddepth: i32, datalayout: DataLayout, mode: ImagePaddingMode ) -> Result<Image2BlobParams>

C++ default parameters

• size: Size()
• mean: Scalar()
• swap_rb: false
• ddepth: CV_32F
• datalayout: DNN_LAYOUT_NCHW
• mode: DNN_PMODE_NULL

pub fn new_def(scalefactor: Scalar) -> Result<Image2BlobParams>

Note

This alternative version of [new] function uses the following default values for its arguments:

• size: Size()
• mean: Scalar()
• swap_rb: false
• ddepth: CV_32F
• datalayout: DNN_LAYOUT_NCHW
• mode: DNN_PMODE_NULL

Trait Implementations

impl Clone for Image2BlobParams

fn clone(&self) -> Image2BlobParams

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Image2BlobParams

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Image2BlobParams

fn eq(&self, other: &Image2BlobParams) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
