Aliasing Reduction via Frequency Roll-Off for Scalable Image/Video Coding
The extracted low resolution video from a motion compensated 3-D subband/wavelet scalable video coder is unnecessarily sharp and sometimes contains significant aliasing, compared ...

Scalable Stereo Video Coding for Heterogeneous Environments
Abstract. In this paper, we propose a new stereo video coding scheme for heterogeneous consumer devices by exploiting the concept of spatio-temporal scalability. We use MPEG standa...

Bit allocation for spatial scalability in H.264/SVC
Abstract—We propose a model-based spatial layer bit allocation algorithm for H.264/SVC in this work. The spatial scalability of H.264/SVC is achieved by a multi-layer approach, w...
