Comparison of Image Retrieval Techniques Using Wavelets and Basic Features

To retrieve query image or sub regions of image, visual techniques are used such as color, shape, texture etc. Relevance feedback is used many times to improve the result and to help the user to express their preference. New approach is proposed in this paper for image retrieval with the help of retrieval techniques likecolor histogram, Match points, Wavelet, using Eigen values. Images from various types of database are first identified by using edge detection techniques .Once the image is identified, then the image is searched in the particular database, then all related images are displayed. This will save the retrieval time and improves retrieval efficiency.. Further to retrieve the precise query image, any of the four techniques are used and comparison is done w.r.t. average retrieval time. Eigen value technique found to be the best as compared with all other techniques.
