Hierarchical Objective Quality Assessment for CS Video in WMSN
International Journal of Distributed Sensor Networks, 2015 Compressive sensing (CS) is a sub-Nyquist sampling way while still enabling exact reconstruction, which is applicable to WMSN. In this paper, based on the characteristic of CS video in WMSN, we proposed a hierarchical objective CS video quality ...
