Research on the image segmentation of icing line based on NSCT and 2-D OSTU

In allusion to increased noise and blurring of icing line images, this paper has proposed a segmentation method based on NSCT and 2-D OSTU, using NSCT to implement denoising processing of image, and introducing combined threshold methods of improved genetic algorithm and 2-D algorithm OSTU for image segmentation, and has described the specific algorithm. The results show that this method can effectively realize the denoising processing of icing images, making accurate extraction of the target, which has reduced the search time, convenient for real time applications.
