Aiming to these presented frequent neighboring class set mining algorithms have some repeated computing and redundancy candidate frequent neighboring class set when these algorithms extract frequent neighboring class set, this paper proposes an algorithm of mining frequent neighboring class set based on increasing sequence, which is suitable for mining frequent neighboring class set of objects in...
Recent studies have demonstrated that language-based static analysis is capable of finding hundreds of bugs in complex real systems. Such static analysis allows users to specify properties in a specification language on demand. Paths in control flow graphs are explored exhaustively against user-defined properties. To avoid the potential path explosion problem, many techniques have been used in practice...
Nowadays, the amount of images increase drastically. Content-based image retrieval (CBIR) has been proposed to efficiently manage these images. Traditional CBIR system extracts the low features of image automatically. Because of the difference between human comprehension and machine, the search results provided by CBIR system always can not satisfy the user's need. So relevance feedback has been used...
In order to retrieve the character images but avoid the OCR system which is limited in some application, a method for Chinese characters retrieval is presented in this paper. It firstly extracts the improved contour feature of Chinese character images, which is used to match roughly. Then, the candidate character images attained above are divided by the centroid of each one. For each part divided,...
In this paper, shot boundary detection (SBD) algorithm based on macroblock and DC image is presented. We get the macroblock type information and simultaneously extract DC images from MPEG compressed domain. The statistics of macroblock type information is applied to coarse detection, and DC images are applied to scrutiny detection. The results of experiments show that our algorithm is efficient, and...
As a traditional type of enterprise form, family business is playing a significant role in economic development at present, the research on which is of great importance. This paper reviews the main advances in the research of family business in China, with emphasis on the definition, management structure, evolution path of family business. At last, this paper puts forward some problems that scholars...
The common zeros problem for blind system identification (BSI) is well known. It degrades the performance of classic BSI algorithms and therefore imposes the limit on the performance of subsequent speech dereverberation. The effect of near-common zeros has recently been studied in terms of channel diversity and the degradation in performance of BSI and multichannel equalization algorithms has been...
