With the development of SOA based on web services, there are more and more web services with same interface and similar function. How to find and choose the best web service is an important problem that all SOA enterprises face. QoS is used to describe the quality criteria of a web service. In this paper, a new algorithm of web service hierarchy base on QoS similarity has been proposed, which is concerned with meeting requirements of service consumers and the satisfaction with load requirement.
An accuracy assessment method that integrates segmentation and classification accuracy is proposed to meet the requirements of object-based image analysis. Segmentation errors are measured by establishing the relation...

Image matching is an important question in computer vision, however, due to the large viewpoint and similar regions, there exist false matches. A robust matching method-DelTri is proposed. Based on the initial matching of Scale Invariant Feature Transform, the matched keypoints are respectively triangulated to create the triangulation net, which can express the overlapped physical structure of the objects. The matched triangles can lead to the final matches. Compared with classical RANSAC, experiments show that DelTri can improve the match robustness, including matching accuracy and magnitude efficiency.
