对图像进行分块编码，总共分四块，在matlab7.0中验证可行(Block coding of images, a total of four points in the matlab7.0 verify possible)

ＯＬＴＶ算法是使用一个标记的训练样本实现大量未标记样本的训练，是一个很好的分类器实现。(OLTV is a package for learning with only one labeled training example along with abundant unlabeled training instances, which is sufficient for building a good classifier.)

说明：  基于matlab的颜色特征图像分割的图像检索源程序(Based on the color characteristics of image segmentation matlab image retrieval source)

THIS IS A CODE ABOUT MATLAB
