The proposed network block takes the instance feature and the corresponding predicted mask together to regress the mask IoU. The mask scoring strategy calibrates the misalignment between mask.
This is done by using one mask per keypoint, initializing it to 0 and setting the keypoint location to 1. By doing this, Mask R-CNN can predict keypoints roughly as good as the current leading models (on COCO), while running at 5fps. Cityscapes. They test their model on the cityscapes dataset Mask R-CNN.

In the first part of Mask R-CNN, Regions of Interest (RoIs) are selected Mask R-CNN has the identical first stage, and in second stage, it also predicts binary mask in addition to class score and bbox. The mask branch takes positive RoI and predicts mask using a fully convolutional network (FCN). In simple terms, Mask R-CNN = Faster R-CNN + FCN. Finally, the loss function is
In order to fulfil both face detection and segmentation tasks from the image to overcome the drawbacks of the existing methods, a face detection and segmentation method based on improved Mask R-CNN (G-Mask) is proposed in this paper. In particular, our scheme introduces Generalized Intersection over Union (GIoU) [ 26 The mask scoring strategy is inspired by the AP metric to use pixel-level Intersection-over-Union between predicted mask and its ground truth mask, denoted by Mask IoU. Mask Scoring R-CNN's implementation is conceptually simple: Mask R-CNN with a MaskIoU prediction network named MaskIoU Head, taking both the output of the mask head and RoI.

At last, we tested the model on different defects categories
Mask R-CNN. Mask R-CNN is an instance segmentation technique which locates each pixel of every object in the image instead of the bounding boxes. It has two stages: region proposals and then classifying the proposals and generating bounding boxes and masks. It does so by using an additional fully convolutional network on top of a CNN based. The method is based on adapting the Mask R-CNN state-of-the-art visual recognition neural architecture and adding a tree-based search procedure to it. In a supervised setting, the method learns to solve all 68 kinds of geometric construction problems from the first six level packs of Euclidea with an average 92% accuracy Mask R-CNN is Faster R-CNN model with image segmentation. (Image source: He et al., 2017) Because pixel-level segmentation requires much more fine-grained alignment than bounding boxes, mask R-CNN improves the RoI pooling layer (named RoIAlign layer) so that RoI can be better and more precisely mapped to the regions of the original image We have used Mask R-CNN  which is an object instance segmentation model alongside object detection and classification for the problem of road damage detection and classification.
