This report describes a method to reduce unnatural artifacts when producing free viewpoint images by a deformable 3-D mesh model. Hybrid rendering methods that have been proposed in the past mostly used only the geometric consistency. Therefore, discontinuous transformation and misalignment of textures have been still quite visible in generated images. In this report, in order to reduce the unnatural artifacts in generated images, we use not only the geometric consistency but also smoothness constraints on both spatial and temporal mesh deformations. Additionally, discontinuities in textures are avoided by improving the strategy of texture selection for each patch in 3-D model. The effectiveness of the proposed method is demonstrated by comparing with previous method using various scenes. |
