Image Segmentation Image segmentation is a further extension of object detection in which we mark the presence of an object through pixel-wise masks generated for each object in the image. With the help of instance segmentation, objects can be assigned to different classes with pixel accuracy. Why doesn't a parallel circuit violate conservation of energy? Object detection cannot accurately estimate some measurements such as the area of an object, perimeter of an object from image. Instance segmentation combines the advantages of semantic segmentation and object detection. In a nutshell, segmentation uses a "divide and conquer" strategy to process visual input. This allows for more fine-grained information about the extent of the object within the box. Using Mask R-CNN we can perform both Object detection and Instance segmentation.
