Illustration of Fast R-CNN and Faster R-CNN architecture showing shared convolutional feature maps, RoI Pooling, Region Proposal Network (RPN), anchor boxes, and object detection outputs with bounding boxes for cars, trucks, and pedestrians in a city scene.

The Evolution of Object Detection: Fast R-CNN and Faster R-CNN Explained

A complete technical breakdown of Fast R-CNN and Faster R-CNN, covering RoI Pooling, quantization effects, Region Proposal Networks, anchor boxes, IoU labeling, multi-task loss, and why replacing Selective Search with RPN transformed object detection into a fully end-to-end trainable two-stage architecture.
