研究论述，先对图像分割的定义、要求进行简单介绍，然后对阙值化、基于边缘方法、基于区域的方法、基于模型的方法和

基于人工智能的方法等主要的图像分割方法进行研究论述，比较了它们的优缺点。-Image segmentation image analysis and pattern recognition is the primary issue, but also the classic problem of image processing. In this paper, image segmentation methods discussed system, the first definition of image segmentation, called for a brief introduction, then the threshold of, based on the edge of the approach, region-based methods, model-based methods and methods based on artificial intelligence and other major The study discusses the image segmentation method, compared with their advantages and disadvantages.
