auto photo image recog. and cropping

I am looking for VB - VBA code to be run from with in Excel 2000, on WIn2K, to be able to look at a JPEG picture and "Look" for a white rectangle and determine the edges of the rectangle and then based on finding the edges of 4 rectangles crop out the image between them and save the resulting crop of the jpeg to a unique file name. What I am doing is I am scanning 16mm film with a film scanner and converting it to a movie type format. My scanner will scan in 4 frames at once and I want this program to be able to go thru a directory of 4 frame scanns and turn them into 4 individual JPEG images. The tractor holes in the film scan in as totally white R,G,B=255. I think the program would be able to scan down the image a certain % of the image width and "look" for these white boxes and from there continue until it finds color other than white. Once it finds the 4 holes around one image crop the center protion out and save it to a JPEG file. The image to be cropped will start in the center of the white hole vertically and on the right and left edges horizontally. I would also want a optional input for a % or number of pixels to have the program remove/add additionally. Basically have it make the picture get cropped a little smaller or larger independantly verticaly or horizontally. I attached asample of the clips I am trying to convert. ## Deliverables 1) Complete and fully-functional working program(s) in executable form(Excel spread sheet with code) as well as complete source code, in VB/VBA language, of all work done. 2) Exclusive and complete copyrights to all work purchased.
