Abstract: A system, method and computer program product for real-time insertion of indicia (e.g., an advertisement) into a live (or taped) broadcast. Typically, the invention allow insertion with occlusion onto surfaces such as tennis courts, the wall behind home plate on a baseball field, the grass or turf on a soccer or football stadium, and the like. The occlusion processing described herein can handle multiple colors in the background image during the insertion of the indicia into a video image. The invention can thus adapt to changing light conditions in the video image. The process includes obtaining a video image from a camera. The video image is typically digitized. Next, the pixels within the video image are sampled. A plurality of background colors are then identified for the sampled pixels. An opacity value is then assigned to each pixel in the indicia based on whether the color of a positionally corresponding pixel in the video image is the same color as one of the plurality of background colors.

Abstract: A live video insertion system (LVIS) is disclosed that allows insertion of static or dynamic images into a live video broadcast in a realistic fashion on a real time basis. Initially, natural landmarks in a scene that are suitable for subsequent detection and tracking are selected. The landmarks are typically distributed throughout the entire scene, such as a ballpark or football stadium. The field of view of the camera at any instant is normally significantly smaller than the full scene that may be panned. The LVIS uses a combination of pattern recognition techniques and camera sensor data (e.g., pan, tilt, zoom, etc.) to locate, verify and track target data. Camera sensors are well suited for the searching requirements of an LVIS, while pattern recognition and landmark tracking techniques are better suited for the image tracking requirements of LVIS.
