摘要： A method and apparatus for synthesizing texture images that match the texture appearance of a given digitized sample of an image. This synthesis is completely automatic and requires only the "target" texture image as an input. It allows generation of as much texture as desired so that any object or surface can be covered with the synthesized texture. The apparatus generates texture parameters for the target texture sample image that reflect the texture in that image. These texture parameters are used to modify the noise image such that the modified noise image attains the texture of the target texture image. To further improve the texture of the modified noise image, an image pyramid is constructed for both the modified noise image and the target texture sample image. The apparatus then iteratively updates the modified noise image on a coarse-to-fine basis using the subbands of the image pyramids. The output image is an updated modified noise image that has attained the texture of the target texture sample image.

摘要： An image processing system (10) for imaging a scene (15) to mosaic, selecting a new viewpoint of the scene, and rendering a synthetic image from the mosaic of the scene from that new viewpoint (112). The synthesized image is then combined with a second image (114). The combination of the second image and the synthetic image generates a composite image containing a realistic combination of objects in the second image and the scene. Using the system, a production set or other scene need only be created once, then imaged by the system. Thereafter, through image processing, any view of the scene can be synthesized and combined with separately imaged performers, or other objects to generate the composite image. As such, a production set or other scene can be repetitively reused without recreating the physical scene.
