DOI: 10.1021/acsphotonics.6b00921
Abstract: Recognition, comparison, and analysis of large patterns or images are computationally intensive tasks that can be more efficiently addressed by inherently parallel optical techniques than sequential electronic data processing. However, existing all-optical image processing and… read more here.
