Hello, I’m back with an Advanced Object Detector article! We are now past the amateur stage if and only if you have read through all our previous articles on Object Detection, R-CNN, Fast R-CNN, SPPnet, Faster R-CNN & Mask R-CNN. Although Mask R-CNN is also a tad advanced, we considered learning related to the R-CNN Family of Object Detectors. We are on the right track to mastering Object Detection after learning the building blocks of an Object Detector and have a fair intuition about the mechanism of how various parts are put together for a fully functional Object Detector. We progressed through the R-CNN, Fast R-CNN & Faster R-CNN architectures and understood how evolution happens to improve the accuracy and reduce the inference time taken per image.
