Abstract

This paper is to propose a scalable video coding scheme for adaptive digital hologram video service for various reconstruction environments. It uses both the light source information and digital hologram at both the sending side and the receiving side. It is a resolution-scalable coding method that scales the resolution, that is, the size of the reconstructed image. The method compresses the residual data for both the digital hologram and the light source information. For the digital hologram, a lossy compression method is used, while for the light source information, a lossless compression method is used. The experimental results showed that the proposed method is superior to the existing method in the image quality at the same compression ratio. Especially it showed better performance than the existing method as the compression ratio becomes higher.

본 논문에서는 다양한 재생환경에서 적응적으로 홀로그램 비디오를 서비스하기 위한 스케일러블 코딩 방법을 제안한다. 이 방법은 광원정보와 디지털 홀로그램 모두를 스케일러블 부호화 및 복호화에서 사용하는 방법으로, 복원된 영상의 해상도, 즉 영상의 크기를 스케일링하는 해상도-스케일러블 코딩 방법이다. 이 방법은 광원정보와 디지털 홀로그램 각각의 차영상을 압축하는 방식을 사용하고 있으며, 디지털 홀로그램의 차영상은 손실압축, 광원정보의 차영상은 무손실압축 방법으로 압축한다. 제안하는 방법을 실험한 결과 기존의 방법에 비해 압축률 대비 화질이 매우 우수하고, 특히 압축률이 증가할수록 기존방법보다 월등한 성능을 보였다.
