In HEVC, the structure of coding unit (CU) and prediction unit (PU) is defined, which brings about higher coding efficiency than H.264/AVC. However, the rate distortion (RD) cost calculations of all depths of CUs and partition modes have yielded tremendous coding computational complexity. In order to reduce the complexity, a fast inter-prediction algorithm(More)
—Due to the problems of the new generation of video coding standard HEVC (High-Efficiency Video Coding), such as high computational complexity and the large computation, This paper proposes a fast inter-mode decision algorithm based on image texture features and by using Sobel operator the edge features are extracted from CU which is partitioned by(More)
Distributed Video Coding (DVC) is a new video coding paradigm which has the ability to shift coding complexity from encoder to decoder. State-of-art DVC schemes are mainly based on two-source correlation model and only one correlation channel between side information and wyner-ziv frame is considered. In this paper, multiple-source correlation model is(More)
Distributed video coding (DVC) is a new video coding paradigm derived from Slepian & Wolf's and Wyner & Ziv's information-theoretic results in 1970's. Turbo-code-based Wyner-Ziv codec provides a practical solution to lossy DVC schemes. It is able to provide good Rate distortion (DR) performance while shift complexity burden from encoder to decoder.(More)
Wireless Sensor Networks (WSN) are used in multiplicity arenas which embraces environmental monitoring, healthcare, battle field, biological, home, disaster management and other commercial applications. With the massive progression in the arena of embedded computer and sensor technology, Wireless Sensor Networks (WSN), that is composed of numerous thousands(More)
