A low complexity video coding for combining RFID and video surveillance with padding based DVC

Abstract

Radio frequency identification (RFID) tag has been extensively used in diverse applications, recently. For instance, we may use it to track freights on a warehouse, to catch a thief for lost luggage and to rapidly locate lost children or passengers who fail to arrive on time at the departure gates of major airport. It can also be employed for transmitting multimedia content (especially for video). Presently, many research works focus on designing the RFID tag with high transmission data rate. In this paper we present a new practical scheme, it integrates the video surveillance into RFID tag at range of 250 kbps data rate for video data transmission. We believe that has not been addressed before in the literature. Here the Distributed Video Coding (DVC) scheme is integrated into RFID tag, where the so-called padding-based DVC scheme, proposed by us recently, is deployed. It is known that the padding-based DVC scheme has the advantages of requiring very low complexity and achieving low bit rate. Via computer simulations we show that the proposed scheme can easily work at data rate less than 250 kbps, and achieve better performance (PSNR) than the conventional approaches.
