Position-Sensitive RoI Pooling layer aggregates the outputs of the last convolutional layer and generates scores for each RoI. Unlike RoI Pooling, PS RoI Pooling conducts selective pooling, and each of the kk × kk bin aggregates responses from only one score map out of the bank of kk × kk score maps. With end-to-end training, this RoI layer shepherds the last convolutional layer to learn specialized position-sensitive score maps.
