Video sequences have the rich texture information in practical applications,which makes the extraction of the semantic objects of interest more *** paper presents a video object extraction algorithm based on depth map for multi-view video coding in three-dimensional video *** of all,gradient operators are used to roughly segment color image into flat and texture regions with threshold,so object contours are extracted,while The OTSU algorithm is used to distinguish backgrounds and foregrounds in the color image,which can fill the pixels of semantic *** the corresponding depth map is processed to highlight the human vision interested *** the same time,inter-frame difference is taken into account,which joins the moving objects into foregrounds,and extracts the interested region with morphological ***,object of block level is obtained though combination of operators outlined above and block-process though *** with the existing algorithms,the proposed algorithm does not adopt popular clustering scheme but joins the OTSU algorithm,thus it can effectively avoid lots of computational complexity which the clustering algorithm *** results show that the proposed algorithm can not only extract accurately the semantic objects,but also reduce the computational *** the objects are static or not,the proposed algorithm can get good efficient segmentation.

Web services are used in many Web applications in order to save time and cost during software development process. To peruse Web service response time, a suitable tool is needed to automate the measurement of the response time. However, not many suitable tools are available for automatic measurement of response time. This research is carried out in the context of quality of Web services in order to measure and visualize Web service response time. The method proposed in this research for accomplishing this goal is based on creating a proxy for connecting to the required Web service, and then calculating the Web services response time via the proxy. A software tool is designed based on the proposed method in order to guide the implementation that is still in progress. The tool can be validated through empirical validation using three test cases for three different Web service access situations.

Many practical applications are dynamic over time, which require optimization algorithms not only to converge to optimum as soon as possible but also to track the changing optimum. In this paper, a Cooperative Dual-sw...

User Interface UI is an old subject, but is still a hot research topic. A lot of efforts were put into making the life of designers and authors of UI easier. Declarative UI languages were a major approach for defining and developing UI. The integration and implementation of a standardized presentation layer is the main focus of the work presented here. This paper presents some new development for our business application development framework XMAN. The improvements are related mainly to the presentation layer, aiming at a set of goals such as Standardization, Device-Independency, Platform-Independency and Abstraction. A good part of the paper is dedicated for discussing some important User Interface Declarative Languages UIDLs in order to select the best one that fits the goals.

To motivate users to adopt and use information systems effectively, the nature of motivation should be carefully investigated. People are usually motivated within ongoing processes which include a chain of states such as perception, stimulation, motivation, actions and reactions and finally, satisfaction. This study assumes that the relevant motivation processes should be executed in a proper and continuous manner to be able to persistently motivate and re-motivate people in organizational settings and towards information systems. On this basis, the study attempts to propose possible relationships between this process-nature view of motivation in terms of the common chain of states and the nearly unique properties of information systems as is perceived by users in the sense of a knowledgeable and authoritative entity. In the conclusion section, some guidelines for practitioners are suggested to ease their tasks for motivating people to adopt and use information systems.

As a primitive assumption, if a new information system is able to remind users their old work habits, it should have a better opportunity to be accepted, adopted and finally, utilized. In this paper some theoretical concepts borrowed from psychodynamic theory e.g. ego defenses are discussed to show how such resemblance can be made without necessarily affecting the performance of the new system. The main assertion is a new system should somehow imitate old work habits, not literally, but through following their paces in terms of the order of habitual tensional states including stimulation, defensive actions and satisfactions.
