Instance segmentation of images with PixelLib Instance segmentation of videos with PixelLib Instance Segmentation of Live Camera with Mask R-cnn. Mask R-CNN with OpenCV In the first part of this tutorial, we’ll discuss the difference between image classification, object detection, instance segmentation, and semantic segmentation. In order to do so, let’s first understand few basic concepts. A thing is a countable object such as people, car, etc, thus it’s a category having instance-level annotation. The instance segmentation combines object detection, where the goal is to classify individual objects and localize them using a bounding box, and semantic segmentation, where the goal is to classify each pixel into the given classes. With semantic segmentation all of them would have been assigned the same colour. Instance Segmentation: It differs from semantic segmentation because different instances of the same object are segmented with different color maps. So OpenCV implemented a marker-based watershed algorithm where you specify which are all valley points are to be merged and which are not. The goal of this new task is simultaneous detection, segmentation and tracking of instances in videos. Instance segmentation with OpenCV. Instance Segmentation Results.
