Continue on object detection

Two strategies for object detection

R-CNN: Region proposals + CNN features

Fast R-CNN: CNN features + RoI pooling

Use bilinear interpolation to get the features of the proposal.

Region of interest pooling

Use backpropagation to get the gradient of the proposal.

New materials

Faster R-CNN

Use one CNN to generate region proposals. And use another CNN to classify the proposals.
