Review: Mask R-CNN Models

Instance segmentation is a challenging computer vision task that requires the prediction of object instances and their per-pixel segmentation mask. This makes it a hybrid of semantic segmentation and object detection. It detects and delineates each distinct object of interest appearing in an image. Mask R-CNN model is common for instance segmentation that has several versions for improving this task. We proposed a simple comparison between Fifteenth different version frameworks from Mask-RCNN for object instance segmentation. Our survey representing the difference between the popular versions of Mask R-CNN. The Mask R-CNN method extends Faster R-CNN by adding a branch for predicting an object mask in parallel with the existing branch for bounding box recognition. The results in most versions were implemented on of the COCO dataset that created for instance segmentation tasks.
