I am converting a matlab code into C++ using OpenCV libraries.
Can anyone tell me roipoly matlab function equivalent in OpenCV??
Or how to get the same functionality using OpenCV?
BW = roipoly(I, c, r)
BW = roipoly(I, c, r) returns the ROI specified by the polygon described by vectors c and r, which specify the column and row indices of each vertex, respectively. c and r are of same size.
In my case I want to extract triangular roi from the image, so c and r are of size 3x1.
Can anyone tell me how to do this in C++ using OpenCV??
