how it works

  

SEARCH BY SIMILARITIES

This is a very important features in the VePAIR solution. It allows to identify groups of images containing similar objects such as, for example, the same monument, the same painting, etc. It is important to note that object matched during a similarity search doesn’t need to be identical; PIAR matching algorithm allows to recognize images even when partially distorted, with a different dimension or with a different daylight exposure.

SEARCH A COPY OF AN IMAGE

Searching a copy of an image using VePAIR means searching exactly a specific image with tolerance on the context in which it appear (for example inside a newspaper page), the dimensions (i.e. proportionally smaller or bigger) and color scheme (i.e. transformed in b/w). The copy detection service of VePAIR is the basement of the Copyright Infringement Detection.
