TWO-LAYER IMAGE RESIZING FOR SCALABLE CODEC
"... Resizing compressed images is often needed for different display, storage and transmission. Based on the analysis of energy reserving capacity for different basis vectors, we propose a two-layer downsizing scheme, where the elementary layer represents the low frequency components of the image, while ..."

, while some high frequency details can be recovered from the enhancement layer. The new method provides a solution for low definition image scalable transmission, at the same time, provides a potential tool to rationally recover the high definition information. Experimental results show that the new
MVC BASED SCALABLE CODEC ENHANCING FRAME-COMPATIBLE STEREOSCOPIC VIDEO
"... Existing 3D video solutions take advantages of the 2D video infrastructure, by coding two views of the stereoscopic video content in a frame-compatible manner, such as sideby-side or top-bottom. Content providers and service providers are using the existing 2D video authorizing tools and delivery in ..."

fullresolution 1080p stereoscopic video content. Co-existing of services based on half-resolution stereoscopic video, fullresolution stereoscopic video, as well as full-resolution 2D video is expected in the marketplace. In this paper, a scalable codec is proposed to support the decoding and rendering of frame
Real Time Software Implementation Of Scalable Video Codec
- In Proceedings of the IEEE International Conference on Image Processing
, 1996
"... Scalable video compression is becoming increasingly more important in diverse, heterogeneous networks of today. In our previous work [2], we developed a scalable codec capable of generating bit rates from tens of kilo bits per second to several mega bits per second with fine granularity of available ..."

Energy Scalability and the RESUME Scalable Video Codec
, 2007
"... In the context of the RESUME-project a scalable wavelet-based video decoder was built to demonstrate the benefits of reconfigurable hardware for scalable applications. Scalable video means that the quality of service (QoS), i.e., the frame rate, resolution, color depth,... of the decoded video can e ..."

A Rate-Distortion Optimal Hybrid Scalable/Multiple-Description Video Codec
"... In this paper, we present a rate-distortion optimal hybrid scalable/multiple-description video codec. Traditional scalable codecs produce bitstreams which can be partitioned into layers that form a hierarchy. Thus, in order for a particular layer to be useful to the decoder, all hierarchically highe ..."

CODEC-INDEPENDENT SCALABLE DISTRIBUTED VIDEO CODING
"... In this paper, we introduce novel schemes for scalable Distributed Video Coding (DVC), dealing with temporal, spatial and quality scalabilities. More specifically, conventional coding is used to obtain a base layer. DVC is then applied to generate enhancement layers. The side information is generate ..."

Note that this scalable DVC approach is independent from the codec used to encode or decode the base layer. Simulation results show that most of the proposed schemes outperform non-scalable DVC

"... The distributed video coding paradigm enables video codecs to operate with reversed complexity, in which the complexity is shifted from the encoder toward the decoder. Its performance is heavily dependent on the quality of the side information generated by motio estimation at the decoder. We compare ..."
