关于Ransac算法 RANSAC为Random Sample Consensus，即随机采样一致性算法，是根据一组包含异常数据的样本数据集，计算出数据的数

关于最小二乘法 以下是百度百科的解释：最小二乘法（又称最小平方法）是一种数学优化技术。它通过最小化误差的平方和寻找数据的最佳函数匹配。利用最小

关于libsvm libsvm是台湾大学林智仁(Chih-Jen Lin)教授等开发，它主要用于分类(支持二分类和多分类)和回归，主页主页，下载

PSNR（Peak Signal to Noise Ratio）：峰值信噪比 使用局部均值误差来判断差异，对于两个H*W*C的图像，I1,I2 其中n为采样值的比特数，比如

由于最近做实验用到二值图像连通区域（八连通）标记，刚开始的时候为了验证算法有效性，用了递归的方法（太慢了，而且图像一大就容易栈溢出），最后查
