Hi,
I am working on Image Compression Algorithms. I want to contribute it in scikit-image.
Can I contribute it ?
I am asking this, because I didn't find Image Compression as Requested features on the following link :   https://github.com/scikit-image/scikit-image/wiki/Requested-features
Please guide me.
