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...

Rule-based semantic summarization of instructional videos
We present a new content-based approach to summarize instructional videos. We first redefine "scene" in instructional videos. Focusing on one dominant scene type, that o...

Selective And Scalable Encryption Of Enhancement Layers For Dyadic Scalable H.264/avc By Scrambling Of Scan Patterns
This paper presents a new selective and scalable encryption (SSE) method for intra dyadic scalable coding framework based on wavelet/subband (DWTSB) for H.264/AVC. It has been ach...
