Rate-Distortion and Rate-Energy-Distortion Evaluations of Compressive-Sensing Video Coding

الملخص EN

Compressive-Sensing Video Coding (CSVC) is a new video coding framework based on compressive-sensing (CS) theory.

This paper presents the evaluations on rate-distortion performance and rate-energy-distortion performance of CSVC by comparing it with the popular hybrid video coding standard H.264 and distributed video coding (DVC) system DISCOVER.

Experimental results show that CSVC achieves a poor rate-distortion performance when compared with H.264 and DISCOVER, but its rate-energy-distortion performance has a distinct advantage; moreover, its energy consumption of coding is approximately invariant regardless of reconstruction quality.

It can be concluded that, with a limited energy budget, CSVC outperforms H.264 and DISCOVER, but its rate-distortion performance still needs improvement.
