I am working on nuclei segmentation task on cytology Cells found in Pap Smear Slides. Imagenet weights do not provide enough information to perform the task. Therefore, I want to use Cytoimagenet weights as well, that are proposed in your paper. i want to experiment with various backbones with UNET to perform the task. The problem is that I find currently the weights in github only for efficientnetB0. How can i find them for other backbones ?
