Dual-Stream Transformer with Cross-Attention on Whole-Slide Image Pyramids for Cancer Prognosis. (arXiv:2206.05782v2 [eess.IV] UPDATED)

The cancer prognosis on gigapixel Whole-Slide Images (WSIs) has always been a
challenging task. Most existing approaches focus solely on single-resolution
images. The multi-resolution schemes, utilizing image pyramids to enhance WSI
visual representations, have not yet been paid enough attention to. In order to
explore a multi-resolution solution for improving cancer prognosis accuracy,
this paper proposes a dual-stream architecture to model WSIs by an image
pyramid strategy. This architecture consists of two sub-streams: one for
low-resolution WSIs, and the other …
