Zhang Jin-shui HU Tan-gao · Yaogan jishu yu yingyong · 2011
A new image retrieval algorithm based on color histogram information entropy is presented.Because the traditional method has not considered the symmetrical character of entropy,so it is easy to create mistakes.By using a limited hue value on information entropy the new method can solve this problem well.As to evaluate the accuracy,we used histogram analysis and correlation coefficients,from qualitative and quantitative of two views to make sure accuracy is dependable.The results show that use this method to search for a similar image is possible and have a high accuracy,the correlation coefficients is above 0.95,and in practical application this method also has a good possibility.
