segmentation of an image using frequencies (c++ or python) : I would like to segment this image [image to segment][1] (I want only the bees, I have 100 images like that not labelled). I think that the best way to do that is to use frenquency domai because the bees seems to have specific frequencies. But I'm not sure how to do that. How to find the reght frequencies ? 

Or maybe you think of a better way to do that ? 

Thanks in advance !
