* @brief Down-scales the image using specified scaling factors or dimensions.
|
|
* This function supports both single-channel (CV_8UC1) and two-channel (CV_8UC2) images.
|
|
*
|
|
* @param _src The input image data, type CV_8UC1 or CV_8UC2.
|
|
* @param _dst The output image data, type CV_8UC1 or CV_8UC2.
|
|
* @param dsize The desired size of the output image. If empty, it is calculated using inv_scale_x and inv_scale_y.
|
|
* @param inv_scale_x The inverse scaling factor for the width. If dsize is provided, this parameter is ignored.
|
|
* @param inv_scale_y The inverse scaling factor for the height. If dsize is provided, this parameter is ignored.
|
|
*
|
|
* @note If dsize is not specified, inv_scale_x and inv_scale_y must be strictly positive.
