摘要

视频同步是一项基本的计算机视觉任务，是广泛应用所必需的。3D视频包含两个流，它们同时从不同的角度显示场景，但在许多情况下它们之间表现出不同步。本文研究了左右立体视图的同步问题。我们假设两个流之间的时间偏移(时间差)和几何失真在每个场景中都是恒定的。提出了一种基于分块匹配算法的子帧精度时移估计方法。

ACCURATE METHOD OF TEMPORAL-SHIFT ESTIMATION FOR 3D VIDEO

Video synchronization is a fundamental computer-vision task that is necessary for a wide range of applications. A 3D video involves two streams, which show the scene from different angles concurrently, but many cases exhibit desynchronization between them. This paper investigates the problem of synchronizing the left and right stereoscopic views. We assume the temporal shift (time difference) and geometric distortion between the two streams are constant throughout each scene. We propose a temporal-shift estimation method with subframe accuracy based on a block-matching algorithm.
