炫技的说法是:"Our algorithm achieved sub-pixel level accuracy." Lucas-Kanade Summary Lucas-Kanade其实就是普通的Nonlinear Least Squares。因为图像是离散的函数,所以要利用 1.差分 2.插值 来解决一些离散函数的问题。 Lucas-Kanade算法 算Lucas-Kanade Residual的线性化。但是因为图像是离散函数,我们要利用以下的...

1、Lucas-Kanade 20 Years On: A Unifying Framework: Part 3 Simon Baker, Ralph Gross, and Iain Matthews CMU-RI-TR-03-35 Abstract Since the Lucas-Kanade algorithm was proposed in 1981 image alignment has become one of the most widely used techniques in computer vision. Applications range from...
Lucas-Kanada最初于1981年提出,该算法假设在一个小的空间邻域内运动矢量保持恒定,使用加权最小二乘法估计光流。由于该算法应用于输入图像的一组点上时比较方便,因此被广泛应用于稀疏光流场。 算法原理参考论文:Pyramidal Implementation of the Lucas Kanade Feature TrackerDeion of the algorithm ...
