1. A method of generating a new terrain image, the method comprising:
- generating an original terrain image through a patch-based synthesis from one or more virtual noise-based terrain models and one or more realistic terrain models; and
blending a boundary of the original terrain image to expand the boundary of the original terrain image, wherein blending comprises;
selecting a patch size from the original terrain image;
selecting a patch area from the original terrain image which is calculated to have a minimum matching error between a regularly overlapped boundary area of the original terrain image and that of the selected patch area; and
adding the selected patch area onto the boundary of the original terrain image to complete the new terrain image.

Abstract
A method and apparatus for quickly generating a natural appearing terrain image. The method according to an exemplary embodiment may include generating a new terrain image through a patch-based synthesis from one or more virtual noise-based terrain models and one or more realistic terrain models; and processing blending of a boundary between synthesized terrain images in the newly generated terrain image.

12. An apparatus, configured to synthesize a new terrain image, the apparatus comprising:
-
a first database configured to store one or more virtual noise-based terrain models; a second database configured to store one or more realistic terrain models; a terrain image synthesizer configured to select at least one noise-based terrain model from the first database, select at least one realistic terrain model from the second database, and generate an original terrain image through a patch-based synthesis from the selected terrain models; and a blending processor configured to blend a boundary of the original terrain image to synthesize the new terrain image by selecting a patch size from the original terrain image; selecting a patch area from the original terrain image which is calculated to have a minimum matching error between a regularly overlapped boundary area of the original terrain image and that of the selected patch area; and adding the selected patch area onto the boundary of the original terrain image to synthesize the new terrain image. - View Dependent Claims (13, 14, 15, 16, 17, 18)
