| Title | TUB @ MediaEval 2013 Visual Privacy Task: Reversible Scrambling with colour-preservative Characteristic |
| Abstract | 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 approaches will still be able to automatically distinguish between differently dressed individuals. The evaluations of our results show that the privacy aspect got a very high score in both objective and subjective metrics. Our approach has a lack of intelligibility since it was measured by applying the Histogram of Oriented Gradients which might be fail on scrambled areas since edges are not preserved. |
