Polygon-mamba: Retinal vessel segmentation using polygon scanning mamba and space-frequency collaborative attention

ArXi:2605.10581v1 Announce Type: new Retinal vessel segmentation is crucial for diagnosis and assessment of ocular diseases. Notably, segmentation of small retinal vessels has been consistently recognized as a challenging and complex task. To tackle this challenge, we design a hybrid CNN-Mamba fusion network that integrates polygon scanning mamba and space-frequency collaborative attention mechanism for the detection of small vessels.
