Abstract

A method for image enhancement includes performing a multi-resolution decomposition of an input image, thereby generating multi-resolution transform components associated with different image scales, comprising at least first and second image scales. A multi-resolution reconstruction is performed to generate an enhanced image by applying filter coefficients to the multi-resolution transform components, such that different, first and second filter coefficients are respectively applied to the multi-resolution transform components that are associated with the first and second image scales. The decomposition is typically performed using a forward transformation filter, and the reconstruction uses a reverse transformation filter, which is not necessarily an inverse of the forward transformation filter
