Abstract

Abstract: In order to solve the problem of less features extraction of SURF, an image characteristics extraction algorithm, R-SURF, which is based on histogram equalization and SURF reconstruction is proposed in this paper. This algorithm can extract more features while maintaining good repeatability, and keeping the robust of SURF. Experimental results show that R-SURF has a better performance than that of SURF and C-SURF.

Key words: Speeded Up Robust Feature（SURF） reconstruction, feature extraction, histogram equalization

摘要： 针对SURF算法提取图像特征点较少的问题，提出了一种经直方图均衡化处理，重构SURF尺度空间（R-SURF）的图像特征提取方法。该方法能提高图像特征点检测数目，同时保持较高的匹配率，并且继承SURF算法的良好特性。将算法与SURF和C-SURF算法进行比较实验，结果表明R-SURF具有更好的特征检测能力。
