Abstract:
1. A process for altering images in a scene, the scene comprising a plurality of frames, the process comprising: converting a 2-D point within a first frame of a plurality of frames to a set of 3-D coordinates; designating the set of 3-D coordinates within the first frame as a 3-D target point; designating two or more sets of 3-D coordinates within the first frame as 3-D replacement points; generating a first plurality of sets of 3-D coordinates corresponding to variations in the 3-D target point between the first frame and a second frame within the plurality of frames; generating a second plurality of sets of 3-D coordinates corresponding to variations in the 3-D replacement points between the first frame and the second frame within the plurality of frames; converting the first plurality of sets of 3-D coordinates into a plurality of 2-D target points corresponding to 2-D variations in the 3-D target point from the first frame to the second frame; converting the second plurality of sets of 3-D coordinates into a plurality of 2-D replacement points corresponding to 2-D variations in the 3-D replacement points from the first frame to the second frame; and locating and copying two or more 2-D replacement points to each 2-D target point.
