AB  - Problem statement: This study presents a new, simple and efficient modified Gaussian
mixture model based clustering algorithm for color-texture segmentation. The proposed mixture model
introduces a new component density function which incorporates spatial information and the weighting
factor for neighborhood effect is fully adaptive to the image content. Approach: It enhances the
smoothness towards piecewise-homogeneous segmentation and reduces the edge-blurring effect. An
Expectation Maximization (EM) model fitting Maximum A Posteriori (MAP) algorithm segments the
image by utilizing the pixel’s color and texture features and the captured neighborhood relationships among them. Results: The algorithm simultaneously calculates the model parameters and segments the pixels iteratively in an interleaved manner. Finally, it converges to a solution where the model parameters and pixel labels are stabilized within a specified criterion. Conclusion:The experimental results with synthetic and natural images demonstrate that the proposed method is effective in improving the segmentation and it outperforms the Fusion of Clustering Results (FCR) algorithm, which is the recent popular segmentation approach.
