发明名称 | Blending 3D model textures by image projection | ||
摘要 | An example method and system for blending textures of a composite image formed by a plurality of source images mapped onto a three dimensional model are presented. The composite image is projected to obtain an unblended projected image having textures. The textures are blended to obtain a blended projected image. Both the unblended and the blended projected images are backprojected onto the three dimensional model. A difference is determined between a pixel of the backprojected, blended image and a corresponding pixel of the backprojected, unblended image. The determined difference is then applied to a further corresponding pixel of the composite image to obtain a modified composite image representing a blending of the plurality of source images in the composite image. | ||

主权项 | 1. A method, performed on one or more processors, for blending textures of a composite image formed by a plurality of source images mapped onto a three dimensional model, comprising: projecting the composite image to obtain a two dimensional, unblended, projected image having textures; blending the textures of the unblended projected image to obtain a blended projected image; backprojecting the unblended projected image and the blended projected image onto the three dimensional model; determining a difference between a pixel of the backprojected, blended image and a corresponding pixel of the backprojected, unblended image; and applying the determined difference to a further corresponding pixel of the composite image to obtain a modified composite image representing a blending of the plurality of source images in the composite image. | ||
