Abstract: The invention is a system and method for processing a compressed data stream. The compressed data stream has a first group of source segments and a second group of source segments. For the first group of source segments, it is not necessary to decompress the source segments during the processing, and only status thereof, like timestamps, are needed to be modified. Comparatively, for the second group of source segments, it is necessary to decompress the source segments for successive manipulation. A recompression is then processed on the manipulated data segments. Finally, the resulting first group and second group of segments are combined together to generate a processed compressed data stream. Because of unnecessary decompression and recompression are dispensed with, significant efficiency is obtained and less error propagation occurs during processing the compressed data stream.

Abstract: The present invention discloses an image modeling method, comprising the steps of: providing image data comprising at least a head, wherein the image data of the head is comprised of a skull area; obtaining a first retrieved image data of the image data in the projected area of the skull; obtaining a second retrieved image data of the image data other than the first retrieved image data and a background image; processing the first retrieved image data in a three dimensional image processing technique, which produces three dimensional image data; processing the second retrieved image data to become a two dimensional planar image data set; and displaying the three dimensional image data in the projected area of the skull of the two dimensional planar image data, and combining the three dimensional image data and the two dimensional planar image data to become combined two and three dimensional image data.
