Searching jpeg images and location of objects in images with multiresolution analysis

Multiresolution method of Harold Stone (1999) for calculation of the progressive wavelet correlation using Fourier methods in the wavelet transformation domain is applied for searching and retrieving images from a collection of images in JPEG format. The process of searching is based on the factorization of the DCT matrix as a product of four matrices. Normalized correlation coefficients are used as a measure of the differences between the two images. Experimental section, which includes testing of hundreds of images, refer to: verifying whether a given object is in an image, determining the location of the object in the image, and finding and extracting a given image from a library of images.
