cvCvtColor(img,dst,CV_RGB2YCrCb);
for (int col=0;col<dst->width;col++)
{
for (int row=0;row<dst->height;row++)
{
int idxF = row*dst->widthStep + dst->nChannels*col; // Read the image data
CvPoint pt = {row,col};
temp_ptr2[0] += temp_ptr1[0]* 0.0722 + temp_ptr1[1] * 0.7152 +temp_ptr1[2] *0.2126 ; // channel Y
}
}
但结果是这样的:
请协助我哪里出错了?
