A COUNTER-BASED HOUGH TRANSFORM SYSTEM

The time required to compute the Hough transform (HT) is directly rela ted to the rate at which addresses are generated to update the Hough s pace. The counter-based Hough transform is a method by which the addre ss generation is accomplished by a counting sequence. Dedicated hardwa re is developed to compute the HT for straight line detection using th e counter-based HT method, where the address for the HT is generated a t the clock rate. A new technique is presented for peak detection in t he parameter space of the Hough transform. The idea is to detect peaks dynamically, while updating the Hough space, thus avoiding the need f or a separate time-consuming stage. This approach is simpler and faste r than the common approach, and is easily implementable in hardware.
