Abstract

The Canny edge detector is used as a preprocessing operator in various high-level image processing techniques used in consumer electronics. Many researchers have implemented the Canny edge detector on a field-programmable gate array, which has the same hysteresis thresholding (HT) architecture. However, the use of this architecture can lead to loss of accuracy in highlevel image processing because the correct edge map cannot be obtained. In this paper, we propose a HT hardware architecture that provides the same results as the software implementation of Canny edge detection by using the idea of connected component analysis (CCA) hardware structure.
