We are using TAO’s MaskRCNN for live image segemtation. For our model, we want to increase the default mrcnn_resolution (currently set to [28, 28]) at least by a factor of four, since our postprocessing depends on high-resolution maps. I was able to increase the mask size to [56, 56] but not any higher.
