I am comparing in Python, 2 images A and B by computing various metrics with skimage.measure module, Let's say for example the structural similarity index with compare_ssim(A, B).

Is there a way to apply this mask with skimage.measure (or any other module), or do I have to reimplement those metrics myself to do it ? Thank you ! Continue reading...
