Although many researches have investigated transparent scrambling video techniques, an issue of which transcoding relates to downsizing scrambled video without unscrambling has ha...
Abstract— In this paper, we focus on 2 : 1 spatial resolution downscaling transcoding from MPEG-2 to WMV. We propose two architectures (for sequences with or without B-frames res...
We have implemented several fast and flexible adaptive lapped orthogonal transform (LOT) schemes for underdetermined audio source separation. This is generally addressed by time-...
Abstract— The heterogeneity in the current and future multimedia environment requires an elegant adaptation framework for the production and consumption of different kinds of mul...
