Abstract
A system for editing a digital image comprises a low pass filter for receiving a source image and for filtering high spatial frequency components of the source image to generate a smoothed image. An arithmetic operator unit subtracts color values of the smoothed image from color values of the source image to produce a first image value on pixel-by-pixel basis. A gradient reversal analyzer compares gradient values of the smoothed image to gradient values of the source image and generates a control signal. A boost controller generates a new value for each pixel of a boost parameter map according to the control signal. The boost controller applies the boost parameter map to modify the first image value to generate a second image value. The arithmetic operator unit is further configured to generate an edge enhanced image according to color values of the source image and the second image value.
