As the complexity of the 3G mobile communications environment, the limitation of the wireless transmission frequency band resources, in order to achieve the transmission and reconstruction of low bit rate, high-quality audio signal, a modified EAAC+ mobile audio coding algorithm based on the existing technology of speech or audio bandwidth extension research is presented in this paper. The algorithm...
The SET k-cover problem is an NP-complete combinatorial optimization problem, which is derived from constructing energy efficient wireless sensor networks (WSNs). The goal of the problem is to find a way to divide sensors into disjoint cover sets, with every cover set being able to fully cover an area and the number of cover sets maximized. Instead of using deterministic algorithms or simple genetic...
In scalable video coding, spatial scalability is a layered video representation with different spatial resolutions for the same video signal. Inter-layer motion information prediction is a method of improving coding performance for spatial scalability. In this paper, a multi-domain motion vectors prediction coding method for spatial scalability is proposed based on inter-layer motion information prediction...
In this paper, we propose an effective sequential lossless compression scheme which performs sequentially pixel by pixel in raster-scan order, also so called one-pass scheme as opposed to multiple-pass scheme. The proposed method has two major components: fuzzy neural network predictor and context based adaptive arithmetic coder. The proposed predictor which is based on T-S fuzzy neural network system...
