We present a multi-level partition of unity algebraic set surfaces (MPU-APSS) for surface reconstruction which can be represented by either a projection or in an implicit form. A algebraic point set surface (APSS) defines a smooth surface from a set of unorganized points using local moving least-squares (MLS) fitting of algebraic spheres. However, due to the local nature, APSS does not work well for...
We present a novel approach for upsampling the synthesized image and video texture using a multi-scale joint bilateral filter. Our method is based on the motivation: if the available exemplar texture is used as a prior to upsample the synthesized texture, a high resolution result that better preventing image blurring can be obtained. Our joint bilateral upsampling applies a spatial filter on the synthesized...
We present a fast gradient domain video compositing using hierarchical data structure which subdivides the compositing region into an octree data. To handle large video compositing by solving a 3D Poisson equation, the derived linear system is usually large. To solve the system requires large memory space and long computational time, which makes it intractable on a standard computer. To address the...
