The sp output

I look for some different algorithms/paper that improve HTM spatial pooling and I like to get the same input to these algorithms and compare their output of SP.
can any one help me? for start this experiments,I want first work on binary vector and compare the outputs of different methods using SP, and in second step I want work on MNIST dataset.

I would be grateful if help me and send me some paper with code in this topic.
