The conventional way of text based retrieval systems are now being replaced by the visual content based systems in image retrieval. The image content has several dominant characteristics features like texture,color,shape and it is interesting to research the classification of images on contentbasis with these features. These different descriptor can be combined to form a single feature vector. However, in order to get optimum performance and to reduce the feature dimensionality for making

Single feature describes image content only from one point of view, which will not give a correct result. Fusing multi-feature similarity score is expected to improve the accuracy of system's retrieval performance. Inorder to assign the fusion weights of multi-feature similarity scores reasonably according to an image, the genetic algorithm is applied.
