Comparative Study on Content Based Image Retrieval Based on Color, Texture (GLCM & CCM) Features

With the rapid development of multimedia and network technology, people can access a large number of multimedia information. For people who want to make full use of multimedia information resources, the primary question is how to query the multimedia information of interest. Text query can be applied to multimedia information retrieval, but it has inherent deficiencies. One hand, text annotation of multimedia information will spend a lot of manpower and resources and it is inefficient. On the other hand, annotated text is usually a person's perception of multimedia information. It is subject to impact of individual difference and state of human and environment, and the described results may be more one-sided. In addition, it is clearly incomplete to describe content-rich multimedia information with a small amount of text. Content Based Image Retrieval (CBIR) techniques appeared in 1990s. It solves the above problems well. It uses low-level features like color, texture and shape to describe image content, and breaks through the limitation of traditional text query technique. In this project we propose an image retrieval method based on multi-feature similarity score fusion using both GLCM and CCM. Single feature describes image content only from one point of view, which has a certain onesided. Fusing multi-feature similarity score is expected to improve the system's retrieval performance. Here the retrieval results from color feature and texture feature are analyzed, and the method of fusing multi-feature similarity score is described. For the purpose of assigning the fusion weights of multi-feature similarity scores reasonably. For comparison, of different distance measurement methods and similarity measurements and also the texture features based on both GLCM and CCM methods are implemented. Finally the content based image retrieval based on color feature, texture feature and fusion of color-texture feature similarity score with equal weights.
