An improved Fuzzy C-Means algorithm implementation with robust execution capabilities and superior segmentation performance
This paper addresses the computational intensity and prolonged runtime of traditional FCM algorithms by proposing an enhanced FCM approach. The method involves dividing images into window-sized sub-blocks, extracting feature vectors at the sub-block level for coarse FCM clustering, followed by pixel-level feature extraction and fine segmentation specifically for edge sub-blocks. This hierarchical segmentation strategy significantly improves processing speed and segmentation accuracy through optimized computational resource allocation.
Application Background: The fuzzy c-means algorithm (FCMA), commonly known as FCM, represents one of the most extensively applied and successful fuzzy clustering techniques. It optimizes an objective function to determine membership degrees of sample points to all cluster centers, enabling automatic data classification. Key Technology: FLICM (Fuzzy Local Information C-Means) - an enhanced FCM variant incorporating spatial constraints using a fuzzy factor that balances noise immunity and detail preservation. Implementation typically involves calculating neighborhood-weighted membership functions and iterative centroid updates.
