具有基於神經網路的音訊瞬態/穩態分離和多頻段壓縮器之虛擬低音系統
移動多媒體電子設備的尺寸和厚度減小，嚴格限制了可配置揚聲器的尺寸。因此，很容易犧牲播放的音質，尤其是低音。在本系統中，我們提出了一種基於神經網路的虛擬低音增強系統來解決這個問題。此外...

A Fast Binary Motion Estimation Algorithm for
MPEG-4 Shape Coding
MPEG-4 is a new international standard
for multimedia communication. It provides a set of
tools for object-based coding of natural and
synthetic videos/audios. MPEG-4 also enables
content-based functionalities by introducing the
concept of video object plane (VOP), and such a
content-based representation.
