Developed a new automatic threshold image segmentation algorithm after comprehensively studying the ostu method with maximum variance between two classes and GA principle, with the changes of the GA, the algorithm develops the compute speed and result stability. Finally, the results of the experiments by the our algorithm are showing to compare with the traditional otsu method, then it is concluded that the algorithm is not only higher quility but also quicker compute speed.
