发明名称 WATERMARK DETECTION METHOD FOR BROADCASTING
摘要 <p>It is known that TV-viewers might record personal videos for their arbitrarily selected views in the upcoming consumer electronic product, free-view TV, it is apparent that solutions for copyright and copy protection problems should be proposed for the free-view TV against misusing such content. The proposed method embeds the same watermark into the transmitted multiple-views of the free-view TV by exploiting the spatial masking properties of the Human Visual System. Extraction of the watermark from any virtual view is achieved after correlating this view by a 'rendered watermark', which is obtained through Light Field Rendering, after determining the unknown location of the virtual camera through a homography between focal and image planes.</p>
