Image Retrieval Algorithm Based on Multi-scale Marginal Chain Code Orientation
Lu Ren · Journal of Xinxiang University · 2014
Image retrieval algorithm based on multi-scale marginal chain code orientation was proposed.First,the multi-scale image contour map was obtained by outlining the whole image with different scales.Second,the proportion of each orientation was calculated,that was obtained by counting the map of different chain code orientations.And the mean vector was computed.Finally,the vectorial Euclidean distance was used to measure the similarity.Experimental results showed that the algorithm has merits of high precision and retrieval performance.
