Overlapping patches

Open jafarinia opened this issue 2 years ago • 3 comments

Hi Thanks for the wonderful paper and very clear code. I have a question. Do you think that your model will still work if we give it overlapping patches? (I need to remove healthy patches from a bag of overlapping patches of WSIs on TCGA)

Hi @hussein-jafarinia

Have you checked the image patches shared by Bin? It seems to me that the patches were already extracted with overlap as I saw the same patch repeated. I am confused about the patch extraction step so really appreciate your feedback.

Best regards.

By overlap I don't mean same patches repeating. I mean for example a patch having 50% overlap with other patches in it's horizontal and vertical axes (which is something that some methods on histopathology do at least for their training process) I haven't checked the details of their tiling/patching code for training(deepzoom_tiler.py). But the result of test_crop_single.py isn't overlapping (I've run it) and based on what the paper says and shows in it's figures it seems like their patches aren't overlapping.

it may be not work well in overlapping patches, the same area will influence the distance between the different patches.
