An objective no-reference video quality assessment method is proposed to evaluate the video quality in voice over Internet protocol (VoIP) applications under network distortion. In order to assess the distortions of videos in VoIP applications caused by codec and packet loss, the method evaluates the quality of received videos by calculating the block artifacts and blurring. Video blocking artifacts...
In order to extract facial features effectively, a face recognition method is proposed in this article, which combined with gamma transform and gabor transform on the basis of the traditional gabor filter method. First of all, the face images are processed with gamma transform, which can eliminate the effects of light and other nonlinear factors; and then decompose the face images by improved gabor...

Some technical problems in developing Java Web application software are discussed. With introduction of SH (Struts + Hibernate) middleware, the advantages of SH in J2EE software development are analyzed, and a feasible B/S software architecture is proposed in this paper. The interface coupling between different layers of software architecture reduces the influence on the whole software system caused...
Image Scale, as a tool for product perceptual analysis, has been widely used in the actual design process. However, its object of study that is the psychological experience of people on products is a very vague and mutative notion, image scale is always considered to be instability and unreliability. Using web-based dynamic database can enhance amount of early collected data and summarize this data...
As the quick development of Internet and the complexity of recent traffic, setting up a kind of easily operated Web GIS software makes special sense, which can look through maps, access location information and query shortest routes. On the basis of comparing several kinds of method to develop Web GIS, this paper chose one which is operated-simply and developed-expediently, thatpsilas Web GIS developing...
