Abstract
Method and apparatus for construction and use in real time of a sequence of pixel-to-pixel mappings that define a video image transformation of a sequence of video images in digital animation video image processing and display. A sequence of compressed mappings that approximate the required sequence of pixel-to-pixel mappings is constructred off-line, and this sequence of compressed mappings is stored for subsequent use and is designated by a selected indicium. When that sequence of pixel-to-pixel mappings is to be applied to a chosen set of video image fields, the sequence of compressed pixel mappings is called up by use of the indicium, the compressed mappings are decompressed, and the sequence of decompressed mappings is applied to the chosen set of video image fields in real time.
