A New Threshold Segmentation Method Based on the Genetic Algorithm for Enhancing the Images

According to the degraded phenomenon of images, establishing shot is a gray-scale distribution of some more concentrated and closer to the sky brightness of the region, while the close-range part can tell, the gray distribution is symmetrical. A new threshold segmentation method based on the genetic algorithm for enhancing the misty images is proposed. the method seeks the threshold value using genetic algorithm which segment the establishing shot and the close shot[1]. then two different enhance method are used respectively. At the same time, the moving template processing method is adopted to resolve the edge effect in the flat region, and images are fused to improve the quality of image. The experiment shows that the method proposed above is very effective to improve the degradation of images and can enhance the clearness of images.
