摘要： A method and system are presented for use in real-time insertion of visual effects in a video stream. A reference image is processed by defining a set of reference features, and inserting the visual effects into the reference image. Successive video frames are grabbed in a sequence of video frames, and one of video frames is used as one snapshot image. The snapshot image (s) is/are processed by selecting reference features and determining a reference transformation. 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. These data are utilized to determine an operative transformation between the reference image and either one of the video frames, thereby enabling real-time management of the appearance of the visual effects in the video stream by using the operative transformation for the insertion of the visual effects in other video frames.
摘要翻译：呈现一种方法和系统，用于在视频流中实时插入视觉效果。通过定义一组参考特征并将视觉效果插入参考图像来处理参考图像。在视频帧序列中抓取连续的视频帧，并且将一个视频帧用作一个快照图像。通过选择参考特征并确定参考变换来处理快照图像。独立于快照图像的这种处理，处理快照图像和其他视频帧以确定它们之间的变换序列。这些数据用于确定参考图像和视频帧中的任何一个之间的操作变换，从而通过使用用于插入视觉效果的操作变换来实现对视频流中的视觉效果的外观的实时管理在其他视频帧。

摘要： 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. These data are utilized to determine an operative transformation between the reference image and either one of the video frames, thereby enabling real-time management of the appearance of the visual effects in the video stream by using the operative transformation for the insertion of the visual effects in other video frames.
摘要翻译：呈现一种方法和系统，用于在视频流中实时插入视觉效果。使用至少一个参考图像，其包含要涉及视频流的感兴趣区域。通过在其中定义一组至少几个参考特征来处理参考图像，并且将视觉效果相对于参考图像中的感兴趣区域以视觉效果的期望取向插入到参考图像中。连续的视频帧以几个视频帧的序列被抓取，并且至少一个视频帧被用作至少一个快照图像。快照图像通过从参考特征中选择至少两个进行处理，并且确定快照图像和参考图像之间的参考变换。独立于快照图像的这种处理，处理快照图像和其他视频帧以确定它们之间的变换序列。这些数据用于确定参考图像和视频帧中的任何一个之间的操作变换，从而通过使用用于插入视觉效果的操作变换来实现对视频流中的视觉效果的外观的实时管理在其他视频帧。

摘要： A narrow bandwidth broadcasting system for transmission of video and television via low bandwidth medium such as internet or radio links. To save bandwith, video scenes are separated into foreground and background objects and only foreground objects are sent to the viewers. However, graphical model or real image may be sent as a reference background and updated according to its own movement. The broadcast system also captures the video camera identification, position, orientation and field of view size for each video fields and sends it together with the foreground object to the viewer. The broadcast system also includes an object tracking apparatus, which captures the position in space of objects that appear in the scene. Shuch parameters allow the implementation of a 3-dimensional rendering at the receiver side.
