Live-Wire segmentation algorithm is an interactive tool for efficient, accurate and reproducible boundary extraction which requires minimal user input. But the traditional Live-Wire algorithm is sensitive to noise and inefficient to distinguish between strong and weak edges in the image. To overcome the two drawbacks, this paper proposes an improved Live-Wire algorithm, its cost function is redefined:...
Mesh segmentation or shape decomposition is a crucial step in shape analysis, shape understanding, model retrieval, and shape composition, etc. To yield visually meaningful parts from an object, previous works suggest the concept of the minimal rule and the theory of part salience. However, they mostly rely on an integral of geodesic distance to approximate the part salience, which requires a high...
Web services run in a highly dynamic environment (the Internet) which makes the composite service will face multiple exceptions in its execution. Thus, it needs to take effective actions to deal with the errors causing the exceptions. Then, by such actions, composite service can adapt to the dynamics and complexity of its execution environment. Since accurately identifying the error source which causes...
