Abstract

A novel hybrid image retrieval algorithm, shape-based image retrieval with two angles, is proposed in this paper. The two angles are the direction angle of objects' edges and the relative angle of two lines in objects' boundary approximated with line-pattern. The former is a pixel-level feature while the latter is a line-level feature. These two features are integrated in our algorithm effectively, and they not only represent the detail and whole information of objects, but also are robust under-translation, scaled and rotation version of the database images. Experimental results on an image database with 4000 pictures show our algorithm obtains a good performance.
