Abstract主要从空间量化误差的角度分析直线方向与拟合误差的关系.首先介绍直线的拟合方法,然后定义敏感距离这一度量图像中的直线对移动敏感性的概念.由此出发讨论不同斜率的直线对直线平移的敏感程度,给出敏感移动距离的表达式及证明.对各种直线拟合结果进行实验统计,结果表明拟合误差与敏感距离有着密切的联系.基于直线拟合时方向误差远小于截距误差这一结果,在已知直线斜率以及直线像素点的前提下,提出一种新的估计截距的方法,实验结果表明本文方法更优越.
Other AbstractThe quantization error plays an important role in the field of image processing and computer vision.The relation between the error of line fitting and the line characters,especially the slope of the straight lines,is mainly analyzed.After a simple introduction of the line fitting,the definition of the sensitive space of straight lines is given,and its expression under different conditions is presented and proved.The emulational experiments suggest there is a close relation between the sensitive space and the error of fitting results.The error of intercept is carefully researched as the error of slope is much less than that of intercept.A method to evaluate intercept is presented. The experimental result shows the proposed method outperforms the traditional one.
