Abstract
A method and an apparatus for increasing the contrast resolution of computer-generated images using fractal enhancement techniques. Each image frame is divided into blocks of pixels which are sorted into source and destination lists based on their distance from the transmit focal zone. The source list contains overlapping pixel blocks corresponding to ranges within a predetermined distance of the transmit focal zone (i.e., blocks of high resolution). The destination list contains non-overlapping blocks corresponding to ranges outside the focal zone area (i.e., blocks of lower resolution). For each low-resolution block, a computer searches for a high-resolution block having the same brightness and contrast classes, but having a greater block contrast. The high-resolution block meeting these criteria and having the greatest block contrast is substituted for the corresponding low-resolution block in the image frame.
