An object detector: it picks regions first, then a CNN names them.
R-CNN is like a security guard with a pause button. It circles weird shapes, then zooms in for a closer look.
It finds objects in pictures. It helped launch deep learning detection, but it was slow.
Object Detection
R-CNN splits Object Detection into picking boxes and naming them.
CNN
A CNN pulls visual clues from each picked region.
Computer Vision
R-CNN helped bring deep learning into Computer Vision detection.
