WebJun 19, 2024 · I have formulated a model that outputs pretty descent segmented images by decreasing the loss value. However, I cannot evaluate the model performance in metrics, such as meanIoU or Dice coefficient. In case of binary semantic segmentation it was easy just to set the threshold of 0.5, to classify the outputs as an object or background, but it ... WebFPN is a fully convolution neural network for image semantic segmentation. Parameters: backbone_name – name of classification model (without last dense layers) used as feature extractor to build segmentation model. input_shape – shape of input data/image (H, W, C), in general case you do not need to set H and W shapes, just pass (None, None ... the toys are back in town t shirt
