I am using visual basic 6 with leadtools 14

My program captures image from source.  The source is scanner and I am acquiring image using TWAIN.  Acquired image contain whitish background.  User donot want this background.  For that purpose, I am trimming (Cropping) the image to interested area.  I take input the film size from user for that.

My problem is that, the size of area of interest is not the same all the time.  The film size taken as input from user donot match with actual area of interest.  If I calculate the ratio with actual film with scanned area of interest, it also dosent match all the times.

Size of whole image(with background) also may change.  In this case, my programming crash.  I donot get desired result.

Is there any way to detect area of interest of image.  Or any other way that can trim only area of interest.

Attaching the sample image herewith.  Try it yourself.

Waiting for reply.

Hi,

That post is about subtract background method.

My query in this post is to remove unwanted area from image (Crop it.)

I had attached you the image that is scanned film.  User is only interested in the film and not in the region around it.

So please reply.

Thanks

Attached is a variation of the sample Maen posted in that thread.  It removes the unwanted white area around the image.
