Query-by-Sketch Image Retrieval Using Edge Relation Histogram

In the Query-by-sketch image retrieval, feature extraction method is important, because the retrieval result depend on image feature. In this paper, we propose the query-by-sketch image retrieval using Edge Relation Histogram (ERH) as global and local feature. ERH focuses on the relation among edge pixels, and ERH is shift-, scale-, rotation- and symmetry-invariant feature. This method was applied to 20,000 images in Corel Photo Gallery. Experimental results show that the proposed method is effective in retrieving images.
