Function:HaarFwd

Performs one-level wavelet decomposition of an image using haar basis. The four resultant images are half the width and half the height of the original image

Function

CuviStatus haarFwd(const CuviImage& src, CuviImage& dstApprox, CuviImage& dstDetailX, CuviImage& dstDetailY, CuviImage& dstDetailXY, const CuviStream& stream = CuviStream());

Parameters

Name Type Description src const CuviImage& Input image dstApprox CuviImage& Output approximation image dstDetailX CuviImage& Output horizontal detail image dstDetailY CuviImage& Output vertical detail image dstDetailXY CuviImage& Output diagonal detail image stream const CuviStream& GPU stream ID for execution

Image Type Support

Input	Output
8uC1	8uC1 x 4
8uC3	8uC3 x 4
