Abstract :
In digital implementations of the Hough transform either digital multiplication or table look-up are used in calculations. Equivalent results may be obtained using an analogue representation. Each edge point in the image is used to generate a signal representing the continuous form of the Hough transform for that point. The signal is sampled at regular intervals to provide a discrete sequence of values. It has been shown that such an analogue implementation achieves a significantly better throughput than an equivalent digital implementation. The designed circuit may be integrated as a one-chip hybrid processing circuit.
