摘要

通常用于减少视频分割所涉及的大量计算的一种基本技术是对视频帧的子部分进行选择性处理。然而,这一比例的选择迄今为止是随机的,没有任何正式依据。对这个子部件的特别选择不能总是保证在保证有效分区的同时减少计算量。本文为这些参数的选择提供了一个原则基础,以确保视频序列的有效分割。提出了一种确定最佳窗口大小和最小阈值的形式化方法,以确保在可靠、有效和有原则的基础上做出场景相似度的决策。为了考虑光照变化和视频中可能的运动,提出了使用基于邻域的颜色比特征,从而避免了显式运动补偿操作的巨大计算需求。

A principled approach to fast partitioning of uncompressed video
One basic technique often used to reduce the huge computation involved in video partitioning is by selective processing of a subpart of the video frames. However, the choice of this proportion has so far been made randomly, without any formal basis. An ad hoc selection of this subpart cannot always guarantee a reduction in computation while ensuring effective partitioning. The paper argues for a principled basis for the selection of such parameters to ensure effective and efficient partitioning of video sequences. It presents a formal method for determining the optimal window size and the minimum thresholds which ensure that decisions on scene similarity are made on a reliable, effective and principled basis. To account for illumination variations and possible motion in the video, the use of neighbourhood-based colour ratio features is proposed, which avoids the huge computational requirements of explicit motion compensation operations.
