IMAGE EDITING SYSTEM AND METHOD HAVING IMPROVED AUTOMATIC OBJECT SELECTION

摘要

An image editor stores color pixels for an image to be edited in an image pixel buffer and a lookup register bank. The stored image is displayed on a monitor. An operator uses a mouse to designate a screen path that identifies an object in the image, and pixel position data is detected for the screen path. A programmed computer determines in real time one or more criteria for a search controller on the basis of hue, saturation and luminance variables which are determined from the stored pixel color data for pixels along the screen path. The computer further searches the image pixels to identify the object and its boundaries in accordance with the search controller criteria, and applies color edit actions to the identified object within the image.
