JPEG2000matlab实现 最新的图像压缩标准(JPEG2000matlab achieve the latest image compression standard)

说明：  实现将二进制转换为DNA碱基，以及逆过程(Realize the conversion of binary to DNA base, and the reverse process)

先用PCA降维，在利用支持向量机进行分类，这个分类是二分类，所以PCA的降维降到两维即可分类。(Firstly, PCA dimensionality reduction is used to conduct classification with support vector machine. This classification is binary classification, so the dimensionality reduction of PCA can be reduced to two dimensions for classification.)

完成水果的尺寸形状表面缺陷的判别，BP神经网络的训练判别表面缺陷(Fruit size, shape and surface defects are identified. BP neural network is used to identify surface defects.)

扫描线Zbuffer算法 1。算出模型的包围盒。 2．每条扫描线打点时并不是包围盒内整条线打点，而是先搜索需要刷新的范围， 只是该范围内打点。 (One scan line Zbuffer algorithm. Calculate the model bounding box. 2. Each scan line runs inside the box when not surrounded by the entire line runs, but first need to refresh the scope of the search, but the scope of RBI.)

对监控视频中的目标进行识别，提取背景信息(The target in the surveillance video is identified and background information is extracted)

MATLAB基于贝叶斯的RGB的彩色图像分割(MATLAB Based on Bayesian Color Image Segmentation in RGB)

英文文本的相似度计算，分别从词形、词序、词义等方面进行权重计算，得到相似度结果(English text similarity calculation were re-calculated from the word form, word order, meaning, etc. right, the similarity results)

说明：  利用matlab对图像进行处理，通过形态学开闭运算，实现对光照不均匀啤酒瓶图像进行准确计数(The image is processed by MATLAB, and the image of beer bottle with uneven illumination can be counted accurately by morphological opening and closing operation)

介绍四叉树基于视点LOD算法简化地形的图形编程资料，很有实用性，还带有其它效果的算法(Introduced Quadtree LOD algorithm based on the simplified view of the graphical programming information terrain is very practical, but also with other effects of the algorithm)
