Pseudorandom sequences have important applications in information security, and the generation method of pseudorandom sequence is an important hotspot of research. Because of owning the large amount of the Knight-tour Hamilton cycles in large size Knight-tour graph, a method based on SemiHam algorithm to generate pseudorandom sequence is proposed in this paper. Firstly, use SemiHam algorithm to produce...
Lines and Polygons Overlay Analysis (LP-OA) is an important analysis method that has been widely used in geographic information systems (GIS). In this study, a new algorithm, Uniform Spatial Grid Indexing (USGI), is proposed to study LP-OA. By applying this method, the theoretical position is evaluated and the theoretical results are verified, suggesting that this algorithm can contribute to the software...
Soft-sensors have been widely used for estimating product quality or other key variables. To achieve high estimation performance for soft-sensor design, it is important to select appropriate input or explanatory variables. This paper presents a new feature selection method applied to Soft-sensors. The proposed method, referred to as FCA-ARM (fuzzy clustering analysis-association rule mining). The...
Power consumption is a critical design issue in embedded systems. This paper presents a structural customization approach, targeting two basic design structures for a multiple choice function that is common in an embedded system: tree structure and chain structure. A theoretical comparison between these two structures is performed. We find that the chain structure has a lower area cost and offers...
Power consumption is a critical design issue in embedded processor design. One of common components in the processor is the Arithmetic and Logic Unit (ALU). Usually, ALUs are designed with a combinational logic circuit containing a number of functional components for different arithmetic and logic operations. An ALU can be constructed with a tree or a chain structure. Existing approaches to reduce...
Although the coding mode of non-RDO in H.264 greatly increases the execution speed of intra prediction, shorter execution time is required. A new intra prediction mode decision algorithm is proposed. First, the intra prediction mode of two chroma macroblocks of same location is only decided by one chroma block. Second, the idea of low resolution and SAD criterion are exploited to select the best 16...
To improve codebook quality in the process of vector quantization, the paper proposes a novel codebook generation algorithm which is based on image segmentation using t-mixture models and greedy EM algorithm. Additionally, in the initial codebook generating procedure, the PNN algorithm is used to reduce LBG algorithmpsilas sensitivity to initial codebook. Experimental results show that the proposed...
