Much research has been done mainly in testcase generation and its effect for com-binatorial design approach for testing. This letter presents an algorithm for fault diagnosis basedon the approach. It can conclude that the factors, which cause errors, must be in a very smallrange through analyzing the test cases after testing, and retesting with some complementary testcases. The algorithm can provide a very efficient and valuable guidance for the debugging andtesting of software.

Coverage analysis is a structural testing technique that helps to eliminate gaps in atest suite and determines when to stop testing. To compute test coverage, this letter proposes anew concept coverage about variables, based on program slicing. By adding powers accordingto their importance, the users can focus on the important variables to obtain higher test *** letter presents methods to compute basic coverage based on program structure graphs. Inmost cases, the coverage obtained in the letter is bigger than that obtained by a traditionalmeasure, because the coverage about a variable takes only the related codes into account.

For special purposes such as improving accuracy of Web image retrieval and indexing, it is worth dwelling on how to separate different types of images from Web pages. In this paper, we put forward the concept of Web Image Cleaning and propose an approach of Web Image Cleaning based on decision tree to process images of four classes, Content, Decoration, Advertisement and lab.l. This paper explores a new text feature of Ascription in feature selection to represent the occurrence of particular words and phrases in href and src attributes of an image tag. Furthermore, feature extraction is performed on DOM (Document Object Model) tree of Web documents. Series of experiments showed that the approach applied to Web Image Cleaning system - WICleaner is practical, speedy and accurate, with average cleaning rate of10 26 images /second and overall cleaning accuracy of 86%. If used in detecting content image, overall detecting accuracy of the system is 94.8%, which is an improvement of approximately 10% over existing image classifiers.

Knowledge reduction is an important issue when dealing with huge amounts of data. And it has been proved that computing the minimal reduction of decision system is NP-complete By introducing heuristic strategy, a heuristic genetic algorithm is proposed. A new operator implement is added to heuristic information, and can maintain the ability of classification. The operator is the embodiment of one local research method using heuristic information. So the algorithm can converge quickly and has the ability of optimizing globally. The correctness and effectiveness are shown in the experiments.
Applications of the Hough Transform (HT) have been limited to small-size images for a long time. For large-size images, peak detection and line verification become much more time-consuming. Many HT-based line detectio...
