Low-complexity hardware architecture of traffic sign recognition with IHSL color space for advanced driver assistance systems

This paper presents novel hardware architecture with low-complexity color conversion scheme and parallel processing of red region detection for the applications of automatic traffic sign detection system. By the inherent parallelism of the various red region detections, we designed a fully pipelined architecture implemented on the FPGA platform. The proposed architecture enables a real-time traffic sign recognition (TSR) processing for a full-HD video (2 Mega pixels) at 60 frames per second.
