High-speed cameras explore more details than normal cameras in the time sequence, while the conventional video sampling suffers from the trade-off between temporal and spatial resolutions due to the sensor's physical limitation. Compressive sensing overcomes this obstacle by combining the sampling and compression procedures together. A single-pixel-based real-time video acquisition is proposed to record dynamic scenes, and a fast nonconvex algorithm for the nonconvex sorted l 1 regularizationdoi:10.1117/1.jei.25.6.063003 pmid:29622898 pmcid:PMC5881933 fatcat:xr7bedg3ynb5rgnwha5yd5o2a4
