Claim One:
1. A method of operating a computer system to modify pixel data in a target image, comprising: storing a target image of an object with pixels to be modified in a memory of the computer; storing a source image of the same object in a memory of the computer; classifying pixel data in the source image to identify pixels having similar data values and determining boundaries of local class areas containing pixels that are grouped in a same class; determining a pixel in the target image to be modified; identifying a replacement pixel in the source image having data that will replace the data for the pixel in the target image to be modified; comparing data values for pixels in a local class area in the source image, that includes the replacement pixel, to the data values for pixels in the target image to determine radiometric relationships between the pixel data in the source image and the pixel data in the target image; and modifying the pixel in the target image by replacing the data with the data for the replacement pixel using the determined radiometric relationships.
