Abstract
In this paper, a wavelet-based spatially scalable video coding scheme with in-band prediction is investigated. The discrete wavelet transform is employed for the spatial decomposition of each video frame. A blockwise motion compensated prediction is computed for the individual subbands. For motion compensation the shift-invariant overcomplete discrete wavelet transform is exploited to achieve half-pixel motion vector accuracy. A blockwise decision is made between the coding of the motion compensated prediction error and the corresponding motion vector data and the wavelet coefficients. JPEG 2000 quantization and arithmetic coding are applied to the resulting prediction error. The performance of the motion compensated predictive in-band coder is evaluated for different block sizes and sub-pixel accuracy.
