摘要
浏览图像时,需要了解图像中不同的局部图像之间的联系。当图像较大时,用户往往把很多精力和时间耗费在来回切换局部图像上。该文通过分析虚拟相机在图像空间中的运动轨迹,构造了一条连接两个局部图像域的最优路径,用该路径作为控制参数提取出两个域之间的图像信息,生成一组过渡平滑的图像序列显示给用户。实验结果表明,该方法生成的图像序列过渡自然、光滑,能够使用户快速、准确地获取需要的信息。
When browsing some images, relationship must be known between two local areas of the images. If the image is too large, the user has to spend much of times and vigor on switching between the two local image areas. In this paper, an optimized path is constructed by analyzing the contrail of a virtual camera that moved in the image space and is used as the control parameters to form a sub-image sequence in which every part is smoothly transited to the next. The result shows that each part of the sub-image transited smoothly and naturally, with it the user gets information rapidly and accurately.
