Abstract
In this paper, we consider a representative integral imaging method in glasses-free 3D image processing and propose a prioritized transmission scheme for guaranteeing a received video quality in error-prone environments. According to the correlation of pixels consisting of each voxel of integral image, we set the priority differently and apply the modulation level according to this priority value. That is to say, the corresponding pixels with small variance are set to a high priority and transmitted by using a low level modulation that is robust under transmission errors, but the corresponding pixels with greater variance are set to a lower priority and transmitted by using a high level modulation that has a high bit error rate but fast transmission rate. Result shows that the proposed scheme that applies the error-robust modulation level to the important image bit stream with the high priority improves the peak to sidelobe ratio (PSR) of the received 3D image, compared with a typical method that use the same modulation level without distinction of priorities. 논문 14-39C-05-06 The Journal of Korea Information and Communications Society '14-05 Vol.39C No.05 http://dx.doi.org/10.7840/kics.2014.39C.5.447 447 ※ 이 논문은 2013년도 정부(교육과학기술부)의 재원으로 한국연구재단의 기초연구사업 지원을 받아 수행된 것임(2011-0025424) First Author : Hankyong National University, Department of Electrical, Electronic and Control Engineering, and the Institute for Information Technology Convergence, mjcho@hknu.ac.kr, 정회원 ° Corresponding Author : Hankyong National University, Department of Electrical, Electronic and Control Engineering, and the Institute for Information Technology Convergence, hhchoi@hknu.ac.kr, 정회원 논문번호:KICS2014-03-086, Received March 14, 2014; Revised May 7, 2014; Accepted May 7, 2014 The Journal of Korea Information and Communications Society '14-05 Vol.39C No.05
