  • Patent number: 8483549
    Abstract: A method and system are presented for use in real-time insertion of visual effects in a video stream. At least one reference image is used that contains a region of interest, which is to be involved in the video stream. the reference image is processed by defining a set of at least a few reference features therein, and inserting the visual effects into the reference image with a desired orientation of the visual effects with respect to the region of interest in the reference image. Successive video frames are grabbed in a sequence of a few video frames, and at least one of video frames is used as at least one snapshot image. The snapshot image(s) is/are process by selecting therein at least two from the reference features and determining a reference transformation between the snapshot image and the reference image. Independently of this processing of the snapshot image, the snapshot image and other video frames are processed to determine a sequence of transformations between them.

  • Patent number: 6297853
    Abstract: A system (FIGS. 7 and 8) and method (FIG. 1) for video transmission of active events, for example sports events, having in the background physical images in designated targets, wherein the physical images are electronically exchanged with preselected virtual images, so that objects or shadows actually blocking the same portions of the virtual images, and the motion of players or a ball blocking the physical image will block corresponding regions of the exchanged virtual image, so that the exchanged electronic image will remain in the background of the event, exactly as the original image.

  • Patent number: 6292227
    Abstract: Apparatus for automatic replacement of a billboard in a video image is provided. The billboard comprises a chroma-key surface, and the apparatus includes a video camera for viewing the billboard, and a chroma-key unit operative to detect at least one chroma-key color of the billboard chroma-key surface. A reference color of the chroma-key unit is adjustable to conform to the color of the chrom-key surface, thereby enabling the chroma-key unit to correctly identify the billboard surface and to correctly replace the chroma-key surface of the billboard by a virtual advertisement in a video image with correct occlusion of any foreground object.

  • Patent number: 6271890
    Abstract: A chromokeying panel for use in conjunction with a chromakeying system includes a plurality of first and second location. Each of the first and the second locations has a color within the color of a color keying spectrum of the chromakeying system. In addition, each of the first and the second locations are arranged to define a coded pattern for a computation of a perspective of the chromakeying panel with respect to a camera independently in each video field produced by the camera. The coded pattern may include a plurality of straight lines that intersect to define vertices. The plurality of straight lines may be spaced apart from each other so that for a given vertex, a ratio of the distance of one of the lines extending from the given vertex to a first adjacent vertex, to the distance of another of the lines from the given vertex to a second adjacent vertex is unique.

  • Patent number: 6122013
    Abstract: A chromokeying system includes a store that contains a representation of a known coded chromokeying pattern. The system further includes a frame grabber that grabs a video image including at least a portion of the known coded chromokeying pattern and a foreground subject. A perspective transformation computation unit computes a perspective transformation by comparing the video image of the portion of the coded chromokeying pattern with the known chromokeying pattern. The system may further include a background generation unit that receives a background image and applies the perspective transformation to the background image to produce a transformed background. The portion of the coded chromokeying pattern in the video image can then be replaced by the transformed background to create a composite image.
