Evaluation of the impact of data preprocessing on the quality of segmentation models based on transformers

PyTorch

example

Description

This project focuses on evaluating the impact of low and high frequency distortion as data preprocessing techniques on the quality of segmentation models based on transformers, specifically for brain tumor segmentation. The study compares the performance of UNet with 3D convolutions, UNetR, and VIT with 3D patches, and finds that UNetR is the most stable model against distortions of different frequencies.
