Hello,
im using Unet to perform semantic segmentation (I want to segment liver metastasis). I want to weight 'more' the pixels of the metastasis respect to the background but I can't manage to do it…
Code for creating unet architecture:
lgraph = unetLayers(imageSize, numClasses, 'EncoderDepth', 4);
How can I change the 'classWeights' in lgraph.Layers(end).pixelClassificationLayer in order to do this??
If, for example, I do this:
lgraph.Layers(end).pixelClassificationLayer.classWeights = [2, 0.5];
I receive an error telling me that i have first to put the 'labels' to the 'classes' options in lgraph.Layers(end), but if i do this:
lgraph.Layers(end) = {'metastasis', 'background'};
I receive an error telling that that layer is in 'read only' mode….
Please im getting crazy…
Thanks in advance for any help!
