A simple Spatial Pyramid Pooling layer which could be added in CNN

sppnet-pytorch

SPP layer could be added in CNN model between convolutional layer and fully-connected lay, so that you can input multi-size images into your CNN model.

The function spatial_pyramid_pool() in file spp_layer.py is independent. It could be added in your own models.
