Abstract


Lossless compression is desired especially for professional applications like medical imaging. However, scalability may be necessary to transmit a fast preview of pictures when the channel capacity is limited. Furthermore, there may be the need for random access to single frames of a losslessly reconstructed video. We present and evaluate a lossy-to-lossless scalable video coding system, where the scalability is achieved using a lossy base layer in conjunction with lossless compression of the reconstruction error in the enhancement layer. High Efficiency Video Coding (HEVC) is employed for encoding the base layer. For compression of the enhancement layer we propose a low-complexity scheme called "Sample-based weighted prediction for Enhancement Layer Coding" (SELC). Furthermore, enhancement layer compression using JPEG-LS and the scalable extension of HEVC (SHVC) are evaluated. The performance of scalable coding using each of these three methods is compared to lossless single-layer coding using the Intra Main RExt configuration. Experimental results show that scalable coding with SELC achieves average bitrate savings of 7.3% compared to lossless single-layer coding, while average bitrate reductions of only 6.3% and 3.9% are obtained using JPEG-LS and SHVC, respectively. Concerning runtime, the additional encoder runtimes of SELC and JPEG-LS compared to base layer coding are negligible. In contrast to that, the runtime of the SHVC enhancement layer encoder is much higher and similar to the runtime of the base layer encoder.
