Light field compression using disparity-compensated lifting
نویسندگان
چکیده
We propose a novel approach for light field compression that incorporates disparity compensation into 4-D wavelet coding using disparity-compensated lifting. With this approach, we obtain the benefits of wavelet coding, including compression efficiency and scalability in all dimensions. Additionally, our proposed approach solves the irreversibility limitations of previous wavelet coding approaches. Experimental results show that the compression efficiency of the proposed technique outperforms current state-of-theart wavelet coding techniques by a wide margin.

Light Field Compression Using Disparity-Compensated Wavelet Decomposition
This paper proposes a new scheme for light field compression that incorporates disparity compensation into wavelet decomposition based on lifting. Disparity-compensated wavelet decomposition is firstly applied to exploit similarity between different views. The resulting coefficient images are encoded using shape-adaptive discrete wavelet transform followed by a modified SPIHT coder. The resulta...

We propose a novel approach that uses disparity-compensated lifting for wavelet compression of light fields. Disparity compensation is incorporated into the lifting structure for the transform across the views to solve the irreversibility limitation in previous wavelet coding schemes. With this approach, we obtain the benefits of wavelet coding, such as scalability in all dimensions, as well as...
متن کاملMulti-hypothesis Prediction for Disparity-compensated Light Field Compression
In this paper, we describe a multi-hypothesis prediction technique for disparity-compensated light field compression. Multihypothesis prediction has been used extensively in video compression. In this work, we apply multi-hypothesis prediction to the problem of light field compression. Most current techniques for light field compression utilize some form of disparity compensation with one hypot...
متن کاملData compression for light-field rendering
Two light-field compression schemes are presented. The codecs are compared with regard to compression efficiency and rendering performance. The first proposed coder is based on video-compression techniques that have been modified to code the four-dimensional light-field data structure efficiently. The second coder relies entirely on disparity-compensated image prediction, establishing a hierarc...
متن کاملRate-Complexity Scalable Multi-view Image Coding with Adaptive Disparity-Compensated Wavelet Lifting
Abstract. This paper presents a novel algorithm for rate-complexity scalable multi-view image coding using an adaptive disparity-compensated (DC) wavelet lifting scheme. First, image regions of multi-view images are prioritized by counting matching points. The proposed algorithm selects either Haar, 5/3, or our proposed multiple picture reference DC wavelet lifting adaptively. The selection cri...
