Abstract

We present a method for elimination of global intensity deformation in gray-scale images using contrast control based on image resolution manipulation. During the process, a Gaussian pyramid representation of an input image is constructed by means of low-pass filtering and sampling of successive pyramid levels, where the input image constitutes the first (zero) level of the pyramid. In the second step, a Laplacian pyramid is built, through subtracting successive levels of the Gaussian pyramid. Then, all levels in the Laplacian pyramid are expanded to the original image size and added with weights, to reconstruct the image. An algorithm and a computer routines library written in object programming language C++ are developed.
