How can I sort Mat with col order
I have a Mat element, that I want to sort with col oder, so for example I have:
Mat A ={[2 1], [0 2], [1 2], [0 1]}
So, If I use:
cv::sort(A, dst, CV_SORT_EVERY_COLUMN + CV_SORT_ASCENDING);
They will order each column independently, but the expected result is to order the second column first, then if a draw happens it will sort by the first column:
Actual:
{[0 1], [0 1], [1 2], [2 2]}
Expected:
{[0 1], [2 1], [0 2], [1 2]}
