99% Read Rate is the new Standard

Prime Vision 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 envelopes is now faster and more accurate than ever. The read rate measured on a collection of Dutch stamps exceeded 99%, whilst the error rate has been reduced to close to 0.
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. The speed of comparison was significantly improved 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.
Currently there are 850 stamps logged in the test system. The new solution does not only reach these fantastic performance figures but also does this within lower processing time. The validation of the detection result has been expanded by new techniques 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
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 can 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.
