EasyOCV is an optical character verification tool used for mark inspection. It provides automatic training of the model, adjustable
acceptance levels and a robust gray-scale analysis. EasyOCV is suitable for various mark inspection and label printing verification
applications. EasyOCV has been designed for on-line verification. It can detect blurred, misaligned, distorted or double marks, extra
or missing ink, missing characters or reversed marks as well as contrast problems.

Working Process
|
|
EasyOCV first requires training on the particular marking. During this phase, a good quality template is presented
to the system. An interactive utility allows defining the structure of the template and related acceptance
criteria, in details. The template learnt can be saved for later use.
|
|
When a template model is ready, the inspection may take place. The sample image is processed and the system
first locates the marking, allowing it to be translated, rotated and re-scaled or even sheared with respect to the
template. After location, geometric comparisons are performed and a series of matching scores, called quality
indicators, are computed. When these fall outside of given acceptance intervals, a defect warning is reported.
