Abstract

A system and method for editing digital images includes a processor for storing a digital image of an object and a background. The periphery, or edge, of the object has a first hue, and the background has a second hue. Based upon the difference between the hues and a predetermined hue difference, the processor locates the edge of the object and removes portions of the image (i.e., the background) that are outside the edge. Then, the object can be combined with a preselected background so as to form a composite image. Optionally, the gamma of the image of the preselected background and the gamma of the image of the object can be matched, thereby making the object appear as if it was imaged under the same lighting conditions as the preselected background.
