Abstract

Since privacy issues are becoming important with growth of the video surveillance, many tools are proposed for protection of personal privacy in the video. However, little is understood regarding the effectiveness of such tools and their effect on the underlying surveillance tasks. In this paper, we propose a subjective evaluation methodology that compares several popular privacy protection techniques applied to typical indoor surveillance video. We identify and analyze the tradeoff between the privacy preservation of these tools and the intelligibility of activities in the resulted surveillance video.
视觉隐私过滤器对视频监控清晰度影响的评价
随着视频监控的发展,隐私问题变得越来越重要,人们提出了许多工具来保护视频中的个人隐私。然而,人们对这些工具的有效性及其对潜在监测任务的影响知之甚少。在本文中,我们提出了一种主观评价方法,比较了几种流行的隐私保护技术应用于典型的室内监控视频。我们确定并分析了这些工具的隐私保护与结果监控视频中活动的可理解性之间的权衡。
