Research On The Techniques For Browsing Images Based On Zooming-Panning Mode

Image Browsing is a new method with a great value to scientific researches and practical applications in the field of information visualizing, and it was rapidly developed in recent years.In this paper, the main ideas, the operating ways and the effects of some existed techniques are presented and analyzed in detail. Especially several typical techniques such as Fish-eye views, Zooming-Panning browsing method based on the relationship of time and space, are checked by experiments. Moreover, the existing merits and demerits are compared and discussed from the navigation effects and realization techniques. In the process of research, some advantages have been found in the Zooming-Panning browsing method based on the relationship of time and space. According to it, some suitable background information is offered to the focus of views, and also a good form of visualized show is taken to meet the need of people who scoop information. However, the concrete realization techniques are insufficiency. It could neither make the structure of the visualized show consistent nor display a good effect. Aiming at the statements above, a following-element is created to make up the shortages of this technique in the paper. Its concept and realized formula are given on the theory of geometric optics. We also have extended two standards which are mentioned in the navigation technique of Zooming-Panning browsing method based on relationship of time and space, and then we introduce a new technique named Zooming-Panning navigation images based on Automatic-control route. It has been examined very well by our experiments.Simultaneity, in order to make the following-element meet the special need, that is to say, with strong real-time and high resolving power of navigation techniques, we have researched the images zooming techniques either, and have given a new images enlargement technique named A method of image enlargement based on curves of rational quadratic spline. It has been examined by our experiments that the method could be applied to navigation techniques and worked very well.
