Graph pattern mining is an important part of the emerging social network science, and the research of the maximum clique problem is one of the most important research branches. In the big data environment, the mass of nodes and complexity of edges in the graph set a higher requirement on the speed and accuracy of the maximum clique (MCP) study. In this paper, we present a parallel graph partitioning...
Reflections of windows or glass panes always destroy the photograph that we want to take by camera or phone. The purpose of this paper is to study and put forward a reflection removal algorithm based on GPU. The algorithm is not simply transplanted from CPU onto GPU. In order to make it adapted to the GPU architecture and programming model, we improve on the original method and the improved algorithm...
In this paper, digital image processing is used for detecting and analyzing the printed circuit boardpsilas drill hole and the results is given to determine if PCB (printed circuit board) meets the industrial production requirement. High-resolution optical camera sensors and image processing algorithms are selected for high-precision detection of the position and the number of PCBpsilas drill hole...
Based on time-domain modified Berlekamp-Massey (BM) algorithm, a Reed-Solomon (RS (204,188)) decoder under the DVB-C standard is designed optimally. New pipeline architecture is adopted in this decoder. In addition, finite-field constant multipliers and specially the time-division-multiplex structure used for key equation solution are proposed, which reduce the bulk of circuit and simplify the complexity...
This paper introduces the broadband wireless access technology which is applied in WMAN. And the design of Reed-Solomon (RS (255, 239)) in IEEE802.16a/d FEC based on time-domain Berlekamp-Massey (BM) algorithm is implemented. In this decoder pipeline architecture is adopted. Furthermore, finite-field constant multipliers and specially the time-division- multiplex structure used for key equation solution...
We propose the fast algorithms for image scrambling using multi-dimensional orthogonal transform. The multi-dimensional orthogonal sequence can provide an orthogonal transform for image scrambling and descrambling. This scrambling method has the characteristic of high security because the keys for scrambling and descrambling are a set of the parameters to generate the orthogonal sequence. But the...
