Abstract
Accurate segmentation of medical images is a critical task in the field of healthcare, aiding
in precise diagnosis and effective treatment planning. This project explores the enhancement
of image segmentation models through the integration of advanced attention mechanisms.
Our primary objective is to compare various attention techniques to develop a
lightweight yet highly accurate model suitable for real-time applications. Given the significant
body of work in medical image segmentation, our approach seeks to balance accuracy
with computational efficiency. By incorporating different attention mechanisms and rigorously
evaluating their performance, we aim to identify the optimal strategy for improving
segmentation outcomes. The results demonstrate the potential for improved segmentation
accuracy and efficiency, highlighting the effectiveness of attention-based models in capturing
intricate patterns and dependencies within medical imaging data. We found out in
our work that the CNN-based attention mechanism, or Convformer, effectively overcomes
the issues related to the training conflict between CNNs and transformers. This project
sets the groundwork for future advancements in semi-supervised and weakly-supervised
learning, and we plan to expand our model’s applicability across a broader range of medical
imaging scenarios. Our ultimate objective is to contribute towards the development of
robust, efficient, and adaptable segmentation models that can enhance diagnostic accuracy
and patient care in various medical fields.
