Application Of Image Processing In The Special Large-screen 3-D Film Production

With the rapid development of China socio-economic, needs of cultural and entertainment products are also growing. This paper researchs to enlarge image based on the special large-screen 3D film. Firstly, this paper simply sums up the main existing kinds of conventional and unconventional methods to the interpolation enlargement, and according to needs of the special large-screen 3D film and taking into account the fast and clarity, selects to maintain a clear outline as a method to the technical ideas. Secondly, this paper applies to two new algorithms for the large-screen enlargement. One is a combination of organic of the neighborhood exchange interpolation algorithm and the median filter. The other is a improvement based on the contour interpolation. Finally, in C++ Builder as the development environment, this paper has achieved reading and interpolation enlargement on a image file, and has tested the two new algorithms by a few of examples. The Compared results show the two new methods are successful, the enlarged image outline is clear and the color transition is real and natural.
