影像分割是图象理解的基本问题。传统方法仅仅考虑影像的颜色信息。Jseg算法是将纹理与光谱信息共同考虑的分割算法，有着较好的效果。源代码为Jseg的发明人所作，本人转载。-image segmentation image is the basic understanding of the problem. Just consider the traditional method of image color information. Jseg algorithm is texture and spectral information common to consider the segmentation algorithm, have better results. Source code for Jseg made by the inventor, I reproduced.
