Development of A Hardware Chain Coder for Industrial Vision Systems

One of the major issues of the industrial vision systems is lengthy processing time due to bulky data for image coding. To reduce the processing time, a modified chain coding algorithm is proposed in such a way that it is more suitable for hardware implementation. A hardware chain coder is developed and used for learn and recognizing objects by extracting several features. It is shown that the desired vision system is much faster than a typical software based system so that it may be applicable to real-time industrial operations.
