MediaEval 2014 Visual Privacy Task: Context-Aware Visual Privacy Protection

In this paper, we describe a privacy filter proposed for VPT 2014 in an attempt to provide a context-aware solution. The proposed solution comprises three different techniques applied to the face, skin, and body regions separately. The proposed combination of filtering techniques aimed to produce an adaptive solution and provide an example of a context-aware-like privacy filtering capability. The results demonstrated the effectiveness of the proposed techniques in maintaining a high level of Intelligibility and retaining the appeal of the video i.e. Pleasantness. However the still identifiable gender and race of certain individuals contributed to the perception of lower levels of privacy of the person in the case of some of the video frames.
