Ransac拟合直线和最小二乘法拟合的比较，对初次接触ransac的读者帮助很大-Ransac fitting straight line and the least-squares fitting of the comparison, the initial contact with the readers of great help to ransac

基于matlab的RANSAC算法，主要用来拟合二维直线，同时选出非直线的点用于后续曲线拟合。(The RANSAC algorithm based on MATLAB is used to fit two dimensional lines, and the point of non straight line is selected for the subsequent curve fitting.)
