public class Image2BlobParams
extends Pointer

\brief Processing params of image to blob. It includes all possible image processing operations and corresponding parameters.

See Also:

\note The order and usage of {@code scalefactor} and {@code mean} are (input - mean) * scalefactor. The order and usage of {@code scalefactor}, {@code size}, {@code mean}, {@code swapRB}, and {@code ddepth} are consistent with the function of \ref blobFromImage.
