WebJan 13, 2024 · Ross Girshick, the author of RCNN, came up with the idea of running the CNN just once per image and then finding a way to share that computation across the 2,000 regions. In Fast RCNN, we feed the input image to the CNN, which in turn generates the convolutional feature maps. Using these maps, the regions of proposals are extracted. WebJul 23, 2024 · The Global Wheat Head… Show more We've published baseline scripts for Global Wheat Head Detection challenges using the Mask-RCNN object detection network in Keras. Initially, We've used ResNet-50 backbone of the object detector network. Later integrating weather-like augmentation and incorporate ResNet-101 for better generalization.

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.
