S4VM
S4VM 对传统的S3VM 进行了改进。传统的S3VM 基于低密度假设,它试图找到一个低密度的分界线,
也就是更倾向于决策边界穿过特征空间的低密度区域。S4VM 和S3VM 的不同点在于,S3VM 试图把注意力
集中在一个最优的低密度分界线上,而S4VM 则同时关注多个可能的低密度分界线。之所以这样做,是因为
给定一些有标记的点和大量未标记的点,可能存在着不止一个“间隔”较大的低密度分界线(如图2 ),基于
有限的标记样本,很难决定哪个是最好的。虽然这些低密度分界线都与有限的标记样本吻合,但它们之间差
异很大,因此如果选择错了,会有一个很大的损失,导致性能下降。所以S4VM 试图考虑所有可能的低密度
分界线。 (Over the past decade,
many improved versions are proposed to solve every different specific problem of semi-supervised support vector
machines, for example: to the inefficiency issue, meanS3VM is introduced to performance degenerate problem,
S4VM is proposed)

RegionGrowing
快速的2D/3D区域生长算法,通过对邻近像素进行优先级排队进行加速,效果优于matlab本身的区域生长算法(Native Matlab implementations of region growing algorithms are usually quite slow, especially for 3D input data. This submission is a mex implementation of a 3D/2D region growing algorithm. The region growing process is further accellereated by using priority queues for the neighbourhood pixels.)

image_compress
本程序利用奇异值分解对3通道彩色图像进行压缩分解,具体步骤如下:
压缩过程:
1. 选取子图像大小K值,把图像分解成M×M个子图像,IMG(s),s=1,2,…, M2,其中M=N/K,原始图像IMG大小为N×N。
2. 计算这M2个子图像的平均值average,对每幅子图像减去均值图像得到新图像。
3. 计算相关矩阵R,其元素定义为 。
4. 计算R的特征值与特征向量,计算每幅子图像与最大特征向量的内积,便得到编码,即压缩后的图像。
(This procedure using singular value decomposition of 3-channel color image compression decomposition, concrete steps are as follows: compression process: 1. Select the sub-image size K value, the image is decomposed into M × M sub-image, IMG (s), s = 1, 2, ..., M2, in which M = N/K, the original image IMG size N × N. 2. M2 calculate the average of sub-image average, for each sub-image minus the new images mean images. 3. Calculation of correlation matrix R, defined as its elements. 4. Calculation of the characteristics of R value and eigenvector calculated each sub-image with the largest eigenvector of the inner product, they will have to code, that is, the compressed images.)
