In distributed video coding, the side information (SI) quality plays an important role in Wyner-Ziv (WZ) frame coding. Usually, SI is generated at the decoder by the motion-compensated interpolation (MCI) from the past and future key frames under the assumption that the motion trajectory between the adjacent frames is translational with constant velocity. However, this assumption is not always ...

Permutation Lempel-Ziv complexity (PLZC) is a recently proposed method for analyzing signal complexity. However, PLZC only characterizes the from single scale and has certain limitations. In order to overcome these shortcomings improve performance of feature extraction underwater acoustic signal, this paper introduced coarse graining operation, multi-scale permutation (MPLZC), an automatic hybr...

We present almost linear time (O(n · log |Σ|) time) O(log n)ratio approximation of minimal grammar-based compression of a given string of length n over an alphabet Σ and O(k · log n) time transformation of LZ77 encoding of size k into a grammar-based encoding of size O(k · log n). Computing exact size of the minimal grammar-based compression is known to be NP -complete. The basic novel tool is ...

Wyner-Ziv coding, distributed coding, Viterbi algorithm, forward-backward algorithm, noisy channel A framework for incorporation of a Wyner-Ziv frame coding mode in existing video codecs is presented, to enable a mode of operation with low encoding complexity. The core Wyner-Ziv frame coder works on the Laplacian residual of a lower-resolution frame encoded by a regular codec at reduced resolut...

We present algorithms computing the non-overlapping Lempel–Ziv-77 factorization and longest previous factor table within small space in linear or near-linear time with help of modern suffix tree representations fitting into limited space. With similar techniques, we show how to answer substring compression queries for Lempel–Ziv-78 a possible logarithmic multiplicative slowdown depending on use...

BACKGROUND/AIMS Aflibercept is an approved therapy for neovascular age-related macular degeneration (AMD) and diabetic macular oedema (DME). In vitro and in vivo studies did not detect toxicity to the retinal pigment epithelium cells using the approved cancer protein, ziv-aflibercept. Our purpose is to determine if ziv-aflibercept can be used in AMD and DME without ocular toxicity, to test the ...

Layered Wyner-Ziv Video Coding: A New Approach to Video Compression and Delivery. (August 2007) Qian Xu, B.S., University of Science & Technology of China; M.S., Texas A&M University Chair of Advisory Committee: Dr. Zixiang Xiong Following recent theoretical works on successive Wyner-Ziv coding, we propose a practical layered Wyner-Ziv video coder using the DCT, nested scalar quantization, and ...
