Dear guys;
Below image is generated using this code;
I=bc;
corners = detectHarrisFeatures(I);
[features, valid_corners] = extractFeatures(I, corners);
plot(valid_corners);
someone please guide me how to get the coordination of these points, else using Douglas_peuker algorithm how can i generate support points.
any assist will be appreciated.
