| Abstract: | The theory of grey relation analysis was used to segment color images in a creative way.An algorithm for medical color image segmentation based on maximum entropy threshold and the concept of color grey relational degree images was proposed.The method prevented the problem of color information loss existent in the previous color image segmentation algorithms and some anti-noise capability was obtained by choosing the resolution coefficient and color effect gene.At the same time,the accuracy was increased and runtime was shortened.The experimental results indicate the effectiveness of the algorithm. |
