Abstract
A method of filtering an input image is provided. In a creating action, a boolean tone map is created based on the input image and an array of tone nodes. In a determining action, it is determined whether or not a target pixel is in a tone region by examining the target pixel and a neighboring region of pixels. If the target pixel is in a tone region, in a selecting action, a first base-filter is selected for the tone region. A method of resolution dependent filtering is also provided.
