imagesegmentation is still a crucial problem in image processing. In this paper, we proposed a novel multi-levelimagesegmentation method based on PSNR using artificial bee colony algorithm (ABCA). PSNR is considered as an objective function of ABCA. The best multi-levelthresholds (t(1)*, t(2)*, ... , t(n-1)*, t(n)*) are those which can make the PSNR maximize. Further, we compare entropy and PSNR in segmenting gray-levelimages and noisy images. Through experiments, it is found that the entropy isn't suitable to be applied to segmentation of images with Gaussian noise. So we can conclude that entropy can't be used for noisy imagesegmentation. The experiments results demonstrate our proposed method is effective and efficient.
