Criss-Cross Network for Semantic Segmentation using attention mechanisms.

CCNet (Criss-Cross Network) is a deep learning architecture designed for semantic segmentation tasks, leveraging a novel criss-cross attention mechanism. It efficiently captures long-range dependencies in images by harvesting contextual information from surrounding pixels along criss-cross paths. The core component, the Criss-Cross Attention module, is recurrently applied to aggregate denser and richer contextual information, enabling the network to understand semantic similarities and long-range dependencies more effectively. CCNet demonstrates state-of-the-art performance with GPU memory efficiency and high computational efficiency. Use cases include autonomous driving, medical image analysis, and satellite image processing. The architecture supports PyTorch and offers pretrained models.

The core component that captures contextual information from surrounding pixels in a criss-cross path. It aggregates information from the same row and column for each pixel.
The Criss-Cross Attention module is applied recurrently to capture denser and richer contextual information. Increasing the number of recurrences 'R' improves performance.
