I would be interested, too. Although from the looks of it, it won’t be a trivial project. It will be great to implement the instance segmentation component. I haven’t found that piece in any of the existing implementations of fast/faster RCNN. Everyone seems to stop at object detection.
Also the pytorch ecosystem for segmentation is a bit small, so this could be a big win for pytorch getting a state of the art segmentation model into the model zoo.
