Feature extraction at sensor level in CMOS vision chips
Real-time automatic interpretation of the scene requires high-speed detection and classification of objects and events. In applications like autonomous driving, unsupervised surveillance, privacy-aware monitoring, augmented reality in mobile platforms, or robot vision, this needs to be achieved under a restricted power budget. Conventional camera architectures separate sensing from processing. All the pixel values are converted to digital and stored in memory before operating upon them. In embedded systems this energy waste cannot be afforded. CMOS vision chips provide processing at sensor level in order to anticipate extraction and learning of the relevant features of the image. This concurrency of sensing and processing reduces the amount of data to be handled at early stages, increasing power efficiency.
Ricardo Carmona-Galán is Senior Member of the IEEE. He graduated in Electronic Physics and got a Ph.D. in 2002 in Microelectronics from the University of Seville, Spain. He worked as a Research Assistant at the EECS Department of the University of California, Berkeley and he was Assistant Professor at the School of Engineering of the University of Seville. Since 2005, he is a Tenured Scientist at the Institute of Microelectronics of Seville (CSIC-University of Seville). His main research focus has been on VLSI implementation of concurrent sensor/processor arrays for real time image processing and vision. He has designed several vision chips implementing different focal plane operators for early vision processing. He also held a Postdoc at the University of Notre Dame, Indiana, where he worked in interfaces for CMOS compatible nanostructures for multispectral light sensing. His current research interests lie in the design of low-power smart image sensors, single-photon detection and ToF estimation, and 3-D integrated circuits for autonomous vision systems.
He has coauthored more than 150 journal and conference papers and a book on low-power vision sensors for vision-enabled sensor networks. He is co-inventor of several patents. He has collaborated with start-up companies in Seville (Anafocus) and Berkeley (Eutecus). Ricardo Carmona-Galán is member of the IEEE Circuits and Systems and Solid-State Circuits Societies, the IEEE Sensor Council and the ACM. He has been Associate Editor for IEEE TCAS-I and now is for Springer’s Journal on Real-Time Image Processing. He got a Certificate of Teaching Excellence from the University of Seville. He is Secretary-Elect of the IEEE CASS Technical Committee on Sensory Systems since May 2017. He is the coordinator of a EU H2020 MSCA-funded innovative training network on advanced hardware/software components for integrated/embedded vision systems (ACHIEVE).
