Special issue on advances on smart camera architectures for real-time image processing

In this special issue, we collect the best contributions of two editions of the Workshop on the Architecture of Smart Cameras (WASC) held in Santiago de Compostela (Spain) in 2015, and in Dijon (France), in 2016. Thus, this issue focuses on novel advances in architecture for image understanding, signal and image processing, configurable and FPGA-based architectures, VLSI systems, but also on languages, software environments, and programming tools and applications of smart cameras.
