Organization: Penn State University From: Subject: scanned grey to color equations? Lines: 7 A while back someone had several equations which could be used for changing 3 f iltered grey scale images into one true color image. This is possible because it's the same theory used by most color scanners. I am not looking for the obv ious solution which is to buy a color scanner but what I do need is those equat ions becasue I am starting to write software which will automate the conversion process. I would really appreciate it if someone would repost the 3 equations /3 unknowns. Thanks for the help!!!
