Abstract
A method for enhancing an image is provided. The method generates a plurality of Gaussian images from the image, and generates a first plurality of Laplacian images from the generated Gaussian images, the plurality of Laplacian images constituting a Laplacian pyramid of images. The method generates a histogram for each of the plurality of Laplacian images, and shapes each of the generated histograms using a predetermined probability density function to produce a second plurality of Laplacian images. The method further combines iteratively each of the second Laplacian images with each of the plurality of Gaussian images expanded at each iteration to generate an enhanced image.
