Abstract
Given two video sequences, a composite video sequence can be generated (15) which includes visual elements from each of the given sequences, suitably synchronized (11) and represented in a chosen focal plane. A composite video sequence can be made also by similarly combining a video sequence with an audio sequence. In the composite video sequence, contestants, action figures or objects can be shown against a common background (12) even if the given video sequences differ as to background, with the common background taken from one or the other of the given sequences, for example. Alternatively, a different suitable background can be used, e.g. as derived from the given video sequences, as obtained from another video sequence or image, or as otherwise synthesized.

59. A computer method for generating a composite video sequence from a plurality of given video sequences for display on a display device, wherein each of the given video sequences comprises a representation of a respective one of a plurality of objects with action relative to a respective environment, the method comprising the steps of:
-
(a) forming a background representation, said background representation including a common environment; (b) aligning said video sequence, based on a matching in size and position of elements from the background and/or from the foreground which are present in two video sequences; (c) forming the composite video sequence based on the formed background; and (d) displaying the composite video sequence on the display device. - View Dependent Claims (60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107)

108. A system for generating a composite video sequence from a plurality of given video sequences wherein each of the given video sequences comprises a representation of a respective one of a plurality of objects with action relative to a respective environment, the system comprising:
-
(a) means for forming a background representation, said background representation including a common environment; (b) means for aligning said video sequence, based on a matching in size and position of elements from the background and/or from the foreground which are present in two video sequences with a visual element in another of the given video sequences, wherein said visual elements are background elements; and (c) means for forming the composite video sequence based on the formed background representation; and (d) a display device for displaying the composite video sequence.

109. A tangible medium comprising a representation of computer instructions for generating a composite video sequence from a plurality of given video sequences and displaying the composite video sequence on a display device, wherein each of the given video sequences comprises a representation of a respective one of a plurality of objects with action relative to a respective environment, the computer instructions comprising:
-
(a) instructions for forming a background representation, said background representation including a common environment; (b) instructions for aligning said video sequence, based on a for matching in size and position of elements from the background and/or from the foreground which are present in two video sequences; (c) instructions for forming the composite video sequence based on the formed background; and (d) instructions for displaying the composite video sequence on the display device.

110. A computer method for generating a composite video sequence from a plurality of given video sequences and displaying the composite video sequence on a display device, wherein each of the given video sequences comprises a representation of a respective one of a plurality of objects with action relative to a respective environment, the method comprising the steps of:
-
(a) forming a background representation, said background representation including a common environment, wherein for each video sequence a weighted mask sequence is computed, said weighted mask sequence describing the probability of a pixel to belong to the background; (c) aligning said video sequences, based on a matching in size and position of elements from the background and/or from the foreground which are present in two video sequences; (d) forming the composite video sequence based on the formed background representation; and (e) displaying the composite video sequence on the display device.
