Towards Optimal Patch Size in Vision Transformers for Tumor Segmentation

1 code implementation31 Aug 2023 Ramtin Mojtahedi, Mohammad Hamghalam, Richard K. G. Do, Amber L. Simpson

Although transformers can capture long-range features, their segmentation performance decreases with various tumor sizes due to the model sensitivity to the input patch size.
