论文摘要

传感器的技术进步为数码相机变得越来越无处不在的道路铺平了道路,这反过来又导致了自我录制文化的普及。结果,Internet上的视觉数据量与用户可用时间和耐心的相反方向移动。因此,大多数上传的视频注定要被遗忘并被遗忘在某些计算机文件夹或网站中。在本文中,我们解决了创建流畅快速视频的问题,而不会丢失相关内容。我们提出了一种新的自适应框架选择,该框架的选择为加权最小重建问题。我们的方法使用平滑的框架过渡并填补了各个段之间的视觉空白,加速了第一人称视频,强调相关的细分市场并避免视觉不连续性。在受控视频中进行的实验以及第一人称视频(FPV)的无约束数据集进行的,这表明,在创建快速前进的视频时,我们的方法能够保留与最先进的技术一样多的相关信息和平滑性,但处理时间较少。

Technological advances in sensors have paved the way for digital cameras to become increasingly ubiquitous, which, in turn, led to the popularity of the self-recording culture. As a result, the amount of visual data on the Internet is moving in the opposite direction of the available time and patience of the users. Thus, most of the uploaded videos are doomed to be forgotten and unwatched stashed away in some computer folder or website. In this paper, we address the problem of creating smooth fast-forward videos without losing the relevant content. We present a new adaptive frame selection formulated as a weighted minimum reconstruction problem. Using a smoothing frame transition and filling visual gaps between segments, our approach accelerates first-person videos emphasizing the relevant segments and avoids visual discontinuities. Experiments conducted on controlled videos and also on an unconstrained dataset of First-Person Videos (FPVs) show that, when creating fast-forward videos, our method is able to retain as much relevant information and smoothness as the state-of-the-art techniques, but in less processing time.
