selective search算法提取proposals

This is mostly the code from [Segmentation as Selective Search for Object Recognition](http://koen.me/research/selectivesearch/), downloaded November 2013. I simply needed a way to call this stuff from Python: `selective_search.py` and `selective_search.m` are the only new files. import selective_search_ijcv_with_python as selective_search windows = selective_search.get_windows(image_filenames) To make sure this works, simply `python selective_search.py`.
