摘要

© 2018 by the authors. Licensee MDPI, Basel, Switzerland.Connected component analysis is one of the most fundamental steps used in several image processing systems. This technique allows for distinguishing and detecting different objects in images by assigning a unique label to all pixels that refer to the same object. Most of the previous published algorithms have been designed for implementation by software. However, due to the large number of memory accesses and compare, lookup, and control operations when executed on a general-purpose processor, they do not satisfy the speed performance required by the next generation high performance computer vision systems. In this paper, we present the design of a new Connected Component Labeling hardware architecture suitable for high performance heterogeneous image processing of embedded designs. When implemented on a Zynq All Programmable-System on Chip (AP-SOC) 7045 chip, the proposed design allows a throughput rate higher of 220Mpixels/s to be reached using less than 18,000 LUTs and 5000 FFs, dissipating about 620 μJ.
