Fast and Efficient 3-D Wavelet Based Video Coding Technique
نویسندگان
چکیده
In this paper, an efficient and embedded 3-D wavelet based video coding technique is proposed. The key idea is the use of a composite block-tree hierarchical structure to link blocks of wavelet coefficients in spatial, temporal and color planes in such a way that a large number of the insignificant sets are coded together. The proposed scheme uses block of wavelet coefficients as a basic unit, in contrast to the existing 3-D set partitioning in hierarchical trees (3-D SPIHT) algorithm that uses a single coefficient as a basic unit. Simulation results show a significant performance improvement in coding efficiency and reduction in computational complexity over the 3-D SPIHT video coder. n n ×

On Boundary Effects in 3-D Wavelet Video Coding∗
3-D wavelet-based scalable video coding provides a viable alternative to standard MC-DCT coding. However, many current 3-D wavelet coders experience severe boundary effects across group of picture (GOP) boundaries. This paper proposes a memory efficient transform technique via lifting that effectively computes wavelet transforms of a video sequence continuously on the fly, thus eliminating the ...

متن کاملThree-Dimensional Embedded Subband Coding with Optimized Truncation (3-D ESCOT)
This paper presents an efficient video coding algorithm: Three-dimensional embedded subband coding with optimized truncation (3-D ESCOT), in which coefficients in different subbands are independently coded using fractional bit-plane coding and candidate truncation points are formed at the end of each fractional bit-plane. A rate-distortion optimized truncation scheme is used to multiplex all su...
