I was sorting wallpapers(of hot girls <wink>) and got tired of doing it manually. Thought i will see if some opencv helps.
So far found a function that extracts BestFeatures.
Wrote up a python script to extract best features and create cropped images of the features for all pictures in a given folder.
Here’s the code: https://github.com/anandjeyahar/Miscellaneous/blob/master/opencv_GoodFeatures.py**
