I am looking for ways to track square markers from the scanned tiff page. The markers are placed at the top right and bottom left. These markers will be used to size and offset page to the correct dimensions for further analysis. Do you have the library that can do just that? I have attached the sample illustrate what I am looking to track.

Hi Suri

I'm afraid we do not have a particular method for that. But it looks like you could easily process the scanlines finding a block where 90% of the pixels are black.

Hi,

i need same feature in order to group scanned pages into documents.
Each document starts with a page with a mark.

Do you have an exemple code?
