Residual Reconstruction for Block-Based Compressed Sensing of Video

A simple block-based compressed-sensing reconstruction for still images is adapted to video. Incorporating reconstruction from a residual arising from motion estimation and compensation, the proposed technique alternatively reconstructs frames of the video sequence and their corresponding motion fields in an iterative fashion. Experimental results reveal that the proposed technique achieves significantly higher quality than a straightforward reconstruction that applies a still-image reconstruction independently frame by frame; a 3D reconstruction that exploits temporal correlation between frames merely in the form of a motion-agnostic 3D transform; and a similar, yet non-iterative, motion-compensated residual reconstruction.
