Model Overview

Mask R-CNN is a convolution based network for object instance segmentation. This implementation provides 1.3x faster training while maintaining target accuracy.

Model Architecture

Mask R-CNN builds on top of Faster R-CNN adding a mask head for the task of image segmentation.

The architecture consists of the following:

• ResNet-50 backbone with Feature Pyramid Network (FPN)
• Region proposal network (RPN) head
• RoI Align
• Bounding and classification box head
• Mask head
