Analysis on Image Feature Detection Algorithms
图像特征检测算法的分析与研究

Image feature detection is a key technique in image processing, pattern recognition, content-based image retrieval, and so on. The typical image feature detectors are analyzed. From the viewpoint of information used, the literatures on image feature detection are analyzed systematically, and image feature detectors can be categorized in to two kinds, that is, gradient-based ones and phase-based ones. Characteristics of each kind are discussed. The key issues of the important image feature detector are explained extensively and comprehensively. Based on the survey, some concerned issues needed further research are presented, and the future research trends are also given.
