Recongizing the presence of a signature on a cheque image


We have an application where we are presented with cheque images that can be in color, black and white or gray scale. Our objective is to determine if there is a signature on the cheque or not. Signature, if present will usually be present in the bottom right corner of the cheque image.

Signature can be in different colors but predominantly will be in black or blue. Additionally, there will be some printed text below the signature (usually, the name of the account holder in printed letters - although this is not always the case).

The cheque background could be plain or with a checquered design pattern.

Is there any ABBY SDK or product that will help us with this task?

    Looking at the images depends on your PDF. Some have the images as elements so you can simply find the selector then use OCR on the image. Some is all image based.

    Yes, you can do this in back office but will require that you have correct resolution. To do this, you will probably need to kick off the Process with a Launch Workflow Interactive, and typically 1920x1080 with 32depth is used in parameters.

    No, you can’t look at an image with the application in the background unless it has a selector.

    The steps that I have taken to look for the signature are as follows:
    - change Zoom field in your PDF viewer to ideal view for Image recognition and OCR
    - Use Arrow keys and Pagedown to scroll page
    - Look for image nearby the Signature box like “Please Sign Here” and stop scrolling
    - Set Clipping Region using the found image element to fit around the Signature box
    - Highlight new element’s clipping region for testing
    - OCR using the element to convert to characters and decide if it’s empty or not

    But, like I said this process is what I was able to get working for image only PDFs in my back office environment, and works well I must say.
