To enhance the accuracy and efficiency of polyp segmentation in colonoscopy images.
To improve early detection of colorectal cancer.

Main Methods:

ColonNeXt utilizes a CNN encoder-decoder architecture.
Incorporates a hierarchical multi-scale context-aware network (MSCAN) in the encoder.
Employs a convolutional block attention module (CBAM) and a novel CNN-based feature attention mechanism in the decoder.
Features a refinement module to enhance boundary accuracy.

Main Results:

ColonNeXt achieved high accuracy and efficiency in polyp segmentation.
Demonstrated significant performance improvement over existing methods on standard datasets.
Showcased robustness in handling variations in polyp size, texture, and illumination.

Conclusions:

ColonNeXt establishes itself as a state-of-the-art model for polyp segmentation.
The model's precision and robustness support enhanced early detection of colorectal cancer.
The developed framework offers a promising tool for clinical applications in gastroenterology.
