Object-based video compression scheme with optimal bit allocation among shape, motion and texture
In object-based video, the encoding of the video data is decoupled into the encoding of shape, motion and texture information, which enables certain functionalities like content-b...

An Architecture for Motion Estimation in the Transform Domain
demanding algorithm of a video encoder. It is known that about 60% ~ 80% of the total computation time is consumed for motion estimation [1]. The second is its high impact on the v...

Anisotropic 3-D wavelet packet bases for video coding
Video coding algorithms based on 3-D wavelet transforms exist which have a competitive rate-distortion performance and are very fast because motion compensation is not needed. The...

Video Coding using 3-D Anisotropic Dual-Tree Wavelet Transform
This paper investigates the use of the anisotropic 3-D dualtree discrete wavelet transform (DDWT) for video coding. The 3-D DDWT is an attractive video representation because it i...

Super-resolution of video using key frames and motion estimation
Many scalable video coding systems use frame downsampling in order to reduce complexity and to enable enhancement layers. Super-resolution (SR) can be used to help the up-sampling...
