Title:
【発明の名称】パターン・キー挿入を用いたビデオ合併
Document Type and Number:
Japanese Patent JP3242406
Kind Code:
B2
Abstract:
Disclosed is a technique for deriving a composite video image by merging foreground and background video image data supplied from a plurality of separate video signal sources employing pattern-key insertion, rather than prior-art color-key insertion, for this purpose. Pattern-key insertion involves replacing a first pattern in a video scene with a second pattern. This is accomplished by first detecting the first pattern in the video scene and estimating the pose of this detected first pattern with respect to a reference object in the video scene. The second pattern is then geometrically transformed using the pose estimate of the detected first pattern. Finally, the detected first pattern is replaced with the geometrically-transformed second pattern.
