Hello,

Is there a way to detect if a scanned page (mostly invoices) has a signature using IEVision ?

Thanks

Hi

It would be easier if you showed an example, but for instance, you could reduce the colors in an area to monochrome using thresholding:

And then check if that area is blank:

yes it is always in a certain area.

How I can detect if there is a content in a certain area?

Hi

If the signature is unique and in a non-specified location, then that is probably not possible.

If it is always within a certain area, e.g. a box, then it should be able to detect that there is content.
