Rcnn layers
WebIn RCNN the very first step is detecting the locations of objects by generating a bunch of potential bounding boxes or regions of interest (ROI) to test. In Fast R-CNN, after the CNN … WebThis layer will be connected to the ROI max pooling layer which will pool features for classifying the pooled regions. Selecting a feature extraction layer requires empirical …
