3.AN IMAGE COMPRESSION AND SYNTHESIS SYST EM BASED ON FRACTAL GEOMETRY PRINCIPLE
8.Firstly, we introduced the related background knowledge of Digital Geometry Processing. Then we thoroughly discussed three kinds of algorithms of Digital Geometry Processing,they are DGP algorithms based on relaxation operator, DGP algorithms based on remeshing, DGP algorithms apply for special geometry image, and analyzed advantage and disadvantage of all kinds of algorithms, after that we discussed the Key Technology, mesh simplification, in Digital Geometry Processing.
10.Based on this background,the technology geometry- and image-based hybrid modeling and rendering(GIBHMR)is put forward,which has been emphasized by international academe at the present time.
