Patent

CA 2617652

A video communication system is disclosed which allows one or more of the participants to selectively participate anonymously by scrambling regions of the video of arbitrary shape, such as the face of the participant. Initially, the video content is analyzed to locate an arbitrary shape of interest, such as a human face or part of a human body. Once the region of interest is located, it is scrambled, for example, in conjunction with two well known video coding schemes; MPEG-4 and Motion JPEG- 2000. The arbitrary regions can be scrambled in the image-domain prior to coding, in the transform-domain during coding, or in the bit stream domain after coding.

L'invention concerne un système de communication vidéo permettant une participation sélective et anonyme à un ou plusieurs participant(s) par brouillage de régions de forme arbitraire de la vidéo, telles que le visage d'un participant. Initialement, le contenu vidéo est analysé afin de localiser une forme arbitraire d'intérêt, telle qu'un visage humain ou une partie du corps. Une fois la région d'intérêt localisée, elle est brouillée, par exemple, conjointement avec deux mécanismes de codage bien connus: MPEG-4 et mouvement JPEG- 2000. Les régions arbitraires peuvent être brouillées dans le domaine image avant le codage, dans le domaine des transformées pendant le codage ou dans le domaine de flux binaire après le codage.
