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

摘要

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