Image processing techniques in coded holotags recognition

The problem of recognizing a given object in a scene is of particular interest in the field of industrial automation. Holotags can be used for automated identification in industrial environments. The extraction of coded information written in holotags, using processing techniques, implies different operations which begin by image acquisition using a CCD device followed by processing, to decode and validate the binary coded information. The paper describes the image processing software that was implemented to extract information from coded holotags and proved to solve the practical problems with acceptable performance.
