| Abstract: | In consideration of the object and the background in image under normal distributions, the algorithm of threshold image segmentation based on the maximum variance method was presented. It was testified and compared with the Otsu method and the maximum entropy method. The results showed that this algorithm had many advantages such as high segmentation precision and fast computation speed. |
