Monochromatic Visualization of Multiple Images by Projection Pursuit

Abstract

A visualization method of multiple images by one monochromatic image is presented on the basis of the projection pursuit approach of the inverse process of the anisotropic diffusion which is a method of image restoration preserving intensity edges. The proposed method is derived through successive improvements added onto the principal component analysis, which is one of the most basic projection pursuit schemes. The annealing technique is incorporated into the optimization process of the present method and its convergence properties are analyzed. An application of this method to an example of MRI images of a brain reveals its promising performance.
