[−][src]Function opencv::cudawarping::remap

pub fn remap(
    src: &dyn ToInputArray, 
    dst: &mut dyn ToOutputArray, 
    xmap: &dyn ToInputArray, 
    ymap: &dyn ToInputArray, 
    interpolation: i32, 
    border_mode: i32, 
    border_value: Scalar, 
    stream: &mut Stream
) -> Result<()>

Applies a generic geometrical transformation to an image.

Parameters

  • src: Source image.
  • dst: Destination image with the size the same as xmap and the type the same as src .
  • xmap: X values. Only CV_32FC1 type is supported.
  • ymap: Y values. Only CV_32FC1 type is supported.
  • interpolation: Interpolation method (see resize ). INTER_NEAREST , INTER_LINEAR and INTER_CUBIC are supported for now.
  • borderMode: Pixel extrapolation method (see borderInterpolate ). BORDER_REFLECT101 , BORDER_REPLICATE , BORDER_CONSTANT , BORDER_REFLECT and BORDER_WRAP are supported for now.
  • borderValue: Value used in case of a constant border. By default, it is 0.
  • stream: Stream for the asynchronous version.

The function transforms the source image using the specified map:

block formula

Values of pixels with non-integer coordinates are computed using the bilinear interpolation.
