What is the purpose of the ROI layer in a Fast R-CNN?

Webb16 apr. 2024 · The main purpose of doing such a pooling is to speed up the training and test time and also to train the whole system from end-to-end (in a joint manner). It's because of the usage of this pooling layer the training & test time is faster compared to original (vanilla?) R-CNN architecture and hence the name Fast R-CNN.
