How Prime Vision Stamp Recognition can save costly, unnecessary hours and help recover considerable losses in unpaid revenue

Benefits of Prime Vision Stamp Recognition:

  • Cost savings by enabling revenue protection
  • Recognition of individual or multiple indicia
  • Identification of more than 95% of stamps
  • New stamps can be added easily
  • Customer manages own database with stamp configuration tool
  • Enables detection of under-stamped mail and a multitude of revenue protection applications
  • Module can be integrated in existing systems

We can read not only address labels but also decipher stamps, franking marks, logos and other images printed onto letters (and parcels)

Our R&D team has developed and refined techniques, which allow our customers to increase their read rates significantly. The automatic recognition of printed items on enveloped is fast and accurate. Depending on the case, the read rate on stamps could exceed 99%, whilst the error rate could be reduced to close to 0.

How it works

The object recognition solution is based on comparing information. First we compare descriptions of image patches around detected interest points on the image with descriptions stored in a database. We keep the comparison up to speed by applying innovative search techniques developed by our research team. As a result of this, more target objects can be stored in the database with even more image descriptors, which increases the applicability, increases the detection rate and reduces the error probability at the same time.

We make use of the latest techniques

Over 1.000 stamps can be logged in the system. Our solution reaches these fantastic performance figures within a low processing time. For the validation of the detection result new techniques are used that compare the object with a reference image over the full image area. This ensures that even very similar objects can be distinguished with high certainty. Additional OCR techniques will read text in the objects for the purpose of validation or data gathering.

A configuration tool allows customers to manage their own image database so that all new objects can be added at short notice.

Prime Vision Stamp Recognition offers considerable cost savings

Next to being accurate, the object recognition system of Prime Vision offers postal organizations the potential for considerable cost savings. Not only does it reliably automate another process, it also enables revenue protection to be carried out automatedly, as under-paid mail to be detected and customers can then be charged for the difference in price. And, in common with all Prime Vision developments, this capability is supplied as a module that can be integrated into already existing systems.

Drive Revenue through Artificial Intelligence


Technology is advancing at such a rate that we can’t predict where we will be in a decade. For now, our industry’s vision is based on artificial intelligence. While the speculation of what’s possible is endless, developers have to translate all this potential, invention and innovation into realistic solutions. While it’s great to let the imagination fly, we have to balance indulgence against purpose and benefit.
