Hello,

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

Thanks

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.

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:
