R-CNN (Object Detection). Region-CNN (R-CNN) is one of the state-of-the-art CNN-based deep learning object detection approaches. Based on this, there are fast R-CNN and faster R-CNN for faster speed object detection as well as mask R-CNN for object instance segmentation. On the other hand, there are also other object detection approaches, such as YOLO and SSD. To have object detection, we need to know the class of object and also the bounding box size and location.
