TensorFlow 2 Mask-RCNN?

I can't seem to find a reliable version of Mask-RCNN for TensorFlow 2. The matterport mask-rcnn (https://github.com/matterport/Mask_RCNN) has depreciated Tensorflow 1 code. Does anyone know of TensorFlow 2 implementations of RCNN either based on…

Not correct instance segmentation if bounding box intersects another bounding boxes

I trained Mask-RCNN model by Detectron 2 for only one class for instance segmentation of lines. If the line is located at an angle to the horizon close to 0 or 90 degrees and its bounding box does not intersect the boxes of other lines, then…

How to make Mask-RCNN work with tensorflow version later than 2.5.3?

Predicting with a Mask-RCNN on python 3.8 / 3.9 / 3.10 and tensorflow 2.6+ gives predictions that do not make sense, but with python 3.8 or python 3.9 and tensorflow version < 2.6 everything works just fine. My Problem: I'm using a Mask RCNN in…

'use_multiprocessing=True' in Mask RCNN with Keras 2.x & Tensorflow 2.x

I am using Keras 2.9.0 and Tensorflow 2.9.2 and already managed to make the necessary changes to compile the Mask-RCNN model (there are many compatability issues as it is a 2017 model). The code is running on Colab with GPU. I get now the following…

Eliminate Classification Head in Mask R-CNN

Is it possible to remove the classification head in Mask R-CNN. Despite enabling class-agnostic settings for both bounding box regression and mask prediction, I am still observing classification loss during training. This seems to suggest that the…
