I have some images of butterflies. I've downloaded them from here. A sample is below:
In each image, the most prominent object is the butterfly (with flowers, leaf etc in background). I usually go for contour/edge detection to locate features in image, but in this case these algorithms are not working as I expected.
I want to locate butterfly and bound it with a box, or better, compute its contour. Is there a way to do this automatically using python-opencv or some other tool?
