Image Retrivl Method Based on NMI Invariable Feature
Zhenbing Zeng · Jisuanji gongcheng · 2004
Content-based image retrieval is a hotspot in the research of multimedia database system and digital library. A new image retrieval method based on NMI invariable feature (normalized moment of inertia) of 1-bit image is presented in this paper, which is simple with high efficiency, and has the ability of anti-geometrical distortion while robust to some image processing such as filtering and smoothing etc. to some extent. Experimental results show that it can be used in image retrieval.
