  • Patent number: 10405065
    Abstract: The video processing system provides for automatic selection of video sequences showing goals in a video stream from cameras directed at a playing field. Classification is applied to image content from different foreground positions in an image. The set of classes comprising a first and second class corresponding players of different teams. Medians or averages of the image positions of the local image content assigned to the first and second class are determined. A condition is tested whether the results are on mutually opposite sides of a reference position and a distance between collected positions or distances between the reference position and the first and second collected positions exceed a threshold value. When the test shows that the condition is met, a preceding video sequence is selected, for example for display.

  • Patent number: 8629908
    Abstract: The invention relates to a method for detecting a moving object in a sequence of images captured by a moving camera. The method comprises the step of constructing a multiple number of difference images by subtracting image values in corresponding pixels of multiple pairs of images being based on captured images. Further, the method comprises the step of retrieving a moving object by extracting spatial information of pixels in the multiple number of constructed difference images having relatively large image values. In addition, from a pair of images in the construction step an image is a representation of a high resolution image having a higher spatial resolution than original captured images on which the high resolution image is based.
