Abstract:
1. A method of introducing a graphical feature or effect into one or more video image frames, the method comprising: forming a three dimensional model view of an object plane; calculating a transform matrix for transforming points in the three dimensional model view of the object plane into an image view of the object plane, the image view of the object plane being represented in the one or more video image frames, the one or more video image frames including images of a scene that includes a view of a plurality of objects disposed on the object plane; forming the graphical feature or effect in the three dimensional model view of the object plane; transforming the graphical feature or effect from the three dimensional model view to the image view of the object plane using the transform matrix; identifying each of the plurality of objects within the one or more video image frames; and extracting plural parts of each of the one or more video image frames, each part including a different one of the plurality of objects on the object plane, into which the graphical feature or effect has been transformed, each of the extracted parts including a portion of the graphical feature or effect, wherein calculating the transform matrix includes
