    • A new method of encoding multiple view image information into an image signal (200) is described, comprising: adding to the image signal (200) a first image (220) of pixel values representing one or more objects (110, 112) captured by a first camera (101); - adding to the image signal (200) a map (222) comprising for respective sets of pixels of the first image (220) respective values, representing a three-dimensional position in space of a region of the one or more objects (110, 112) represented by the respective set of pixels; and adding to the image signal (200) a partial representation (223) of a second image (224) of pixel values representing one or more objects (110, 112) captured by a second camera (102), the partial representation (223) comprising at least information of the majority of the pixels representing regions of the one or more objects (110, 112) not visible to the first camera (101). Advantages are less required information for higher precision and increased usability.

    • The invention relates to a method, a device and a computer program product for tracking a movement of an object or of a person. Tracking the movement of a person or an object by means of electronic video frames is conventional but fails if the person of object experience a sudden significant change in its translational velocity. The suggested method comprises a first step of grabbing a sequence of digital video frames and thereby capturing the object or person. At the same time measurement values of a parameter are obtained, said measurement values being indicative for the movement of the object or person being tracked by the digital video frames. In the next step the video frames are processed by means of processing logic whereby the processing logic uses a block matching algorithm, said block matching algorithm defining a pixel block in a frame and searching for this pixel block within a search area within a next frame and whereby the location of the search area within the next frame is dynamically adapted on the basis of the measurement values. The invention provides the advantage that an electronic processing of digital video frames by means of a block matching algorithm can be carried out even in those cases in which there are large changes in the velocity of the tracked object or person.
    • 本发明涉及用于跟踪物体或人的移动的方法,装置和计算机程序产品。 通过电子视频帧跟踪人物或物体的移动是常规的,但是如果物体的人的平移速度突然发生显着的变化,就会失败。 所提出的方法包括:抓取数字视频帧序列,从而捕获对象或人物的第一步骤。 同时获得参数的测量值,所述测量值指示由数字视频帧跟踪的对象或人物的移动。 在下一步骤中,通过处理逻辑处理视频帧,由此处理逻辑使用块匹配算法,所述块匹配算法在帧中定义像素块并在下一帧内的搜索区域内搜索该像素块,并且 由此基于测量值动态地调整下一帧内的搜索区域的位置。 本发明提供的优点是,即使在跟踪对象或人的速度有很大变化的情况下,也可以通过块匹配算法进行数字视频帧的电子处理。
