In this paper, a car recognition algorithm based on fuzzy clustering of multiple features of car image is proposes. Firstly main color model and image pyramid are used to get complete contour of car. Then round rate, Fourier descriptor, direction ratio and circumference ratio are extracted and analyzed in detail. Afterwards all features are combined into a feature vector and fuzzy clustering is used...
This paper study how to establish topology graphs from a topology embryonic graph with the help of computer in type synthesis of parallel mechanisms. The character of TGs are depicted by character arrays. Define what is isomorphic CAs in virtue of the concept of character string. Then put forward the new approach to identify isomorphism of CAs by using identification matrix. The program finding all...
In this paper, we propose a new strategy for online placement algorithm on 2D partially reconfigurable devices, termed the quad-corner (QC). The main differences between our algorithm and related art are quad-corner spreading capability and dynamical searching sequences. Moreover, existing algorithms do not evaluate their algorithms with real hardware tasks; we do experimentations with real hardware...
This paper proposes a car recognition algorithm based on multiple features of contour. Firstly, canny operator is used to get the edge of the image. Afterwards, image pyramid is used to shrink the image so that the contour will be single-edged and complete. Then, from a point in the contour, travel the whole contour to gain the Fourier descriptors and direction ratio from the traversal sequence. At...
As XML gradually becomes the standard of the data exchange and expression for Internet, how to accurately access the data stored in the XML documents has already been a crucial problem to be solved. At first, the paper illustrates the structure of Patricia Tries and gives the search method of Patricia Tries based on analyzing the difference between Tries tree with Patricia Tries. Afterwards, the dictionary-based...
Proteins use conserved binding motifs associated with relatively unconserved flexible amino acid sequences as mobile tethers for interacting molecules, as exemplified by C-terminal tether sequences of bacterial chemotaxis receptors. We describe here a bioinformatics pipeline to discover new instances of flexible tethers and their binding motifs. C-terminal regions of all proteins in subsets of bacteria...
One of the major challenges in the post-genomic era is to determine all DNA-binding transcription factors (TFs) and their regulatory binding sites (motifs) within the genomes. To discover the relationship between the motifs and changes in gene expression, we propose a new algorithm, co-miner (correlation miner). Correlation rules are generated based on the expression profiles of genes with significant...
