Abstract
In this paper we provide a lightweight video compression scheme, Low Overhead Spatio-Temporal Video compression (Lost-Vision) scheme which is done through inter-frame and intra-frame compression. In inter-frame compression redundant frames are removed by a proposed interpolation search-based method and a lightweight edge detection technique. Then intra-frame compression is done by a proposed adaptive column dropping technique modifying an existing technique namely ICCD. At the receiver end, we propose two reconstruction filters targeting to improve reconstruction quality. Performance of our scheme in terms of energy efficiency and reconstruction quality is evaluated both theoretically and practically. In practical implementation, the proposed video compression scheme is assessed in a real environment with different terrains using a smartphones/tablet-based DTN-like network. A Comparison of our scheme with three recent works on video compression shows our scheme's dominance over the competing works with 52%, 45.6% and 53% energy in saving yet maintaining acceptable reconstruction quality.
