中文简介: | 动态事件,如家庭聚会、音乐会或体育赛事,通常由一群人拍摄。通过这种方法获得的静态图像集具有丰富的动态内容,但缺乏准确的时间信息。我们提出了一种照片排序的方法——暂时对一组由一组未校准的相机异步拍摄的静止图像进行排序。在分析(或可视化)静态图像捕获的动态场景时,照片排序是一个必不可少的工具。该方法的第一步检测图像上对应的静态和动态特征点集。静态特征用于确定图像对之间的极轴几何,每个动态特征投票决定其出现的图像的时间顺序。动态特征提供的部分顺序不一定一致,我们使用秩聚合将它们组合成全局一致的图像时间顺序。我们展示了成功的照片测序的几个具有挑战性的图像集合使用许多移动电话。 |
课程简介: | Dynamic events such as family gatherings, concerts or sports events are often captured by a group of people. The set of still images obtained this way is rich in dynamic content but lacks accurate temporal information. We propose a method for photo-sequencing --- temporally ordering a set of still images taken asynchronously by a set of uncalibrated cameras. Photo-sequencing is an essential tool in analyzing (or visualizing) a dynamic scene captured by still images. The first step of the method detects sets of corresponding static and dynamic feature points across images. The static features are used to determine the epipolar geometry between pairs of images, and each dynamic feature votes for the temporal order of the images in which it appears. The partial orders provided by the dynamic features are not necessarily consistent, and we use rank aggregation to combine them into a globally consistent temporal order of images. We demonstrate successful photo sequencing on several challenging collections of images taken using a number of mobile phones. |
