Image Retrieval Based on Spatial Color Histogram of Oriented Graph
Lin You-quan · Journal of Hangzhou Dianzi University · 2013
Based on color and edge,image retrieval using the spatial color histogram of the same or the similar oriented graph was proposed.Firstly,transform HSV color space to Cartesian coordinate system.Secondly,the color orient is extracted by using Sobel detection operator.Thirdly,obtain the same or the similar oriented graph.Finally,compute the spatial color histogram of this oriented graph.This method combines color,orient and spatial information.And the experimental results show that the proposed method is more efficient in retrieving the user-interested images.
