With the development of technology and Internet,people need more and more information.The carrier of information is also changed from the original text into the current image, video, etc. Image retrieval plays an increasingly important role in the field of study. This paper is a study of image retrieval based on color and texture features, the main algorithms include color histogram,color moment,gray level co-occurrence matrix(GLCM) and Tamura texture features,etc.Then it made further improvements that combined color histogram and Tamura texture features method (we made Tamura texture retriveal again based on color histogram firstly) based on search results.Experimental results demonstrate that the rates of retriveal by comprehensive approach is higher than using a single method.
