There are two ways of using the normalized correlation coefficients. The first one is for locating objects in the JPEG image, and the second one for locating given image in an image library. In the paper we apply normalized correlation coefficients for searching JPEG images. We make use of progressive wavelet correlation along with Fourier method. The image is searched step by step. The searching consists of three incremental steps, each of which quadruples the number of correlation points. The process can be halted at any stage if the intermediate results indicate that the correlation will not result in ca match
