Abstract: The present disclosure relates to a method for stitching video recordings of a sport event. The method comprising the steps of: providing a first video recording and a second video; determining a first and second pluralities of feature points in the first and a second video recordings, wherein the first and second pluralities of feature points have a common set of feature points; identifying an element portion of a physical element present in at least one of the video recordings, wherein the element portion is associated with a physical size; estimating a feature location of feature points of the common set based on an in-frame position of the element portion in the video recordings and on the physical size of the element portion; and stitching the first video recording and the second video recording based on the feature location to obtain a panoramic video of the sport event.

Abstract: A computer-implemented method is provided for automated detection of a moving area of interest, such as a ball, in a video stream of filed sports with a common object of interest encompassing a plurality of players and the object of interest. Images of a sports ground are captured by means of a video camera system producing a video stream which is digitally processed to continuously identify a detected concentration of action within the boundaries of the field. The concentration of action in the field is determined based on an estimated position of the object of interest in at least one frame of the video stream. Players' postures or orientations may be detected to improve the accuracy of the determination of the object of interest.
