基于对角线偏移的SURF算子改进
An Improvement of SURF Based on Diagonal Offset
摘要
Abstract
Since SURF only is partly invariant for illumination,if it is applied into the variable illumination changing scene,the perform-ance of features and matching will decrease highly. In order to overcome the drawback,make a deeper analysis about how the illumination influences the performance of SURF,and improve the original SURF with uniform illumination by combining the diagonal-offset model. The improved algorithm has a stronger ability about invariant for illumination,so that can get stable feature points even under a big illumi-nation changing and match.关键词
