The function xf::cv::absDiff computes the absolute difference between each individual pixels of an xf::cv::Mat and a cv::Mat, and returns the difference values in a cv::Mat.
API Syntax
template <int PTYPE, int ROWS, int COLS, int NPC>
void absDiff(cv::Mat &cv_img, xf::cv::Mat<PTYPE, ROWS, COLS, NPC>& xf_img, cv::Mat &diff_img )
