MediaEval 2012: Scrambling Faces for Flexible Privacy Preservation using Image Background Self-similarities
نویسندگان
چکیده
In this paper we present a system for preserving the privacy of individuals in video sequences by obfuscation of facial appearance, so as to render recorded people unrecognizable. Therefore we address the following two problems: automatic face detection and scrambling of face region. A multi-resolution access control scheme is used in order to decrease the visual quality of regions containing faces, according to the user access right. The proposed scrambling scheme is achieved by combining a self-VQ coding module and a bit masking algorithm.

MediaEval 2012 Visual Privacy Task: Applying Transform-domain Scrambling to Automatically Detected Faces
In this paper, we describe our approach and discuss evaluation results for the MediaEval 2012 Visual Privacy task. The goal of the task is to obscure faces of people visible in provided surveillance clips to preserve their personal privacy. We also additionally assume, although it is not explicitly stated in the task description, that the privacy protection should be done in an automated way an...

This paper describes our participation in the Visual Privacy Task of MediaEval 2014, which aims to obscure human occurrence in image sequences. As a result the recorded person should be unrecognisable, but if needed the obscured areas can be recovered. We use an approach which models the background and pseudo-randomly scrambles pixels within disjunct foreground areas. This technique is reversib...
متن کاملPrivacy Protection Filter Using StegoScrambling in Video Surveillance
This paper introduces a new privacy filter adopted in the context of the DPT (Drone Protect Task) at MediaEval Benchmark 2015. Our proposed filter protects privacy by visually replacing sensitive RofI (Regions of Interest) by its shapes. A combination of steganography and scrambling is used in order to make this filter. Once the scrambling is applied on the pixels of the RofI, its MSB (Most Sig...

This paper describes our participation in the Visual Privacy Task of MediaEval 2013, which aims to obscure human occurrence in image sequences. As a result the recorded person should be unrecognisable. We use an approach which pseudo-randomly scrambles pixels within specified regions. This technique is reversible and preserves the colour characteristic of each region. So, colour-based approache...
متن کاملMediaEval 2012 Visual Privacy Task: Privacy, Intelligibility through Pixellation and Edge Detection
In this paper, we describe a method that can protect privacy in video footage by automatically obscuring faces. In order to retain some level of intelligibility, a specific filter has been added for showing some facial features without revealing the person’s identity.
