R-CNN: Region-based Convolutional Neural Network
R-CNN (Region-based Convolutional Neural Network) was an epoch-making model in 2013. It successfully combined CNN with classical computer vision techniques for object detection and broke the previous record. R-CNN is now an old model, but it’s essential to know its origin in studying the subsequent development in object detection.
If you are new to object detection, please refer to this article that explains the difference between image classification and object detection. Otherwise, let’s get started with an overview of R-CNN.
Ross Girshick
Ross Girshick, the central figure behind R-CNN, was a postdoc at the University of California, Berkeley, at the time. Then, he worked for Microsoft for a while and now belongs to Facebook (Meta) AI Research (FAIR).
Note: Yann LeCun tweeted that FAIR now stands for Fundamental AI Research.In addition to R-CNN, Ross Girshick researched and developed Fast R-CNN and Faster R-CNN. He was involved in developing YOLO (first version only) with Joseph Redmon. He co-authored the paper for Mask R-CNN with Kaiming He (famous for Kaiming Initialization, or He Initialization). The latter also participated in the Faster…
