SPPNet(Spatial Pyramid Pooling in Deep Convolutional Networks for Visual Recognition) 1. Region proposals : Extract RoI(2,000) apply with Selective Search to the image 2. CNN : Input the image to ConvNet without crop & warp, get the Feature map(256). 3. Scale-down all the RoI(2,000) and map on the Feature map. 4. RoI Feature : Extract the RoI from the Feature map. 5. SPP : Apply the RoI Feature ..
