Sažetak
Subpixel accurate motion compensated temporal filtering introduces a significant coding gain in scalable 3D wavelet video codecs. The influence of the chosen subpixel interpolation technique has not yet been fully analysed in the context of resolution scalability. That problem is addressed in this paper. It is shown that support for increased accuracy and resolution adaptive spatial interpolation needs to be featured in a scalable video decoder, when low resolution sequences are targeted. Using the proposed resolution adaptive filters based on sinc kernels leads to improved decoding performance at low resolution in the sense of achieving higher quality while reducing the complexity of the system.
