Background:

• Accurate segmentation of liver images is crucial for medical diagnosis and treatment planning.
• Existing fuzzy cellular neural networks (FCNN) show promise but can be improved for complex image segmentation tasks.

Purpose of the Study:

• To introduce and evaluate the Advanced Fuzzy Cellular Neural Network (AFCNN) for enhanced CT liver image segmentation.
• To improve boundary integrity and recall accuracy in segmented liver images.

Main Methods:

• Developed AFCNN by enhancing the FCNN architecture to better utilize contour and gray-level information.
• Proved the convergent property and global stability of the AFCNN.
• Applied an AFCNN-based NDA algorithm to segment 5 CT liver images, comparing results with an FCNN-based NDA algorithm.

Main Results:

• AFCNN demonstrated superior performance over FCNN in CT liver image segmentation.
• Key metrics such as boundary integrity and recall accuracy were significantly improved with AFCNN.
• The Binary_rate performance index was consistently higher for AFCNN compared to FCNN.

Conclusions:
