Hardware implementation of the Hough Techniques for Irregular Colour and Grey-level Pattern Recognition

This paper presents a hardware implementation of the Hough technique applied to the tasks of irregular colour and grey-level pattern recognition. The presented method is based on the Hough Transform with a parameter space defined by translation, rotation and scaling operations. An essential element of this method is the generalisation of the Hough Transform for grey level and colour images. The technique simplifies the application of the Hough Transform to irregular patterns recognition tasks. The hardware implementation accelerates the calculations considerably and may be used in computer vision systems, for example, in a robotic system.
