Material replacement has wide application throughout the entertainment industry, particularly for postproduction make-up application or wardrobe adjustment. More generally, any low-cost mock-up object can be processed to have the appearance of expensive, high-quality materials. We demonstrate a new system that allows fast, intuitive material replacement in photographs. We extend recent work in ...

This article presents the first version of a talking head, called MOTHER (MOrphable Talking Head for Enhanced Reality), based on an articulatory model describing the degrees-offreedom of visible (lips, cheeks...) but also partially or indirectly visible (jaw, tongue...) speech articulators. Skin details are rendered using texture mapping/blending techniques. We illustrate here the flexibility o...

A color image with an associated normal stored for each pixel is a useful datatype. It improves on images since geometry information is also present while at the same time it avoids all the complexity present in a 3D mesh. In this report, we investigate editing these enhanced images. Local shape deformation operators are presented. Global operators are developed using texture synthesis methods....

Dynamic textures can be defined as repetitive patterns that exhibit both spatial and temporal coherence. The problem of capturing this intrinsic behavior of a dynamic texture by learning a model from an input video is addressed. Application of a model-based method to dynamic texture synthesis, video compression and videoediting is demonstrated. Results from a method for segmentation of multiple...

A method of manifold representation for human faces with pose variations is proposed. Our model consists of mappings between 3D head angles and facial images separately represented in shape and texture, via sub-space models spanned by principal components (PCs). Explicit mappings to and from 3D head angles are used as processes of pose estimation and transformation, respectively. Generalization...

We develop a direct and accurate approach for local resampling in vector fields, and then use the approach to synthesise textures on 2D manifold surfaces directly from a texture exemplar. Regular-grid patches produced by the local resampling are used as building blocks for texture synthesis. Then, texture optimisation and patch-based sampling are generalised to synthesise texture directly in ve...

1 A variety of natural and man-made phenomena can be characterized 2 by repetitive discrete elements. Examples include a stack of fruits, 3 a plate of dish, or a stone sculpture. Although certain results can 4 be produced via existing methods based on procedural or physical 5 simulation, these are often designed for specific applications. Some 6 of these methods can also be hard to control. 7 W...

A novel approach for appearance and geometry completion over point-sampled geometry is presented in this paper. Based on the result of surface clustering and the given texture sample, we define a global texture energy function on the point set surface for direct texture synthesis. The color texture completion is performed by minimizing a constrained global energy using the existing texture on t...

We present a method for synthesizing two dimensional (2D) element arrangements from an example. The main idea is to combine texture synthesis techniques based-on a local neighborhood comparison and procedural modeling systems based-on local growth. Given a user-specified reference pattern, our system analyzes neighborhood information of each element by constructing connectivity. Our synthesis p...

We consider the combined completion of 3D surface relief and colour for the hidden and missing portions of objects captured with 2 1 2 D (or 3D) capture techniques. Through an extension of nonparametric texture synthesis to facilitate the completion of localised 3D surface structure (relief) over an underlying geometric surface completion we achieve realistic, plausible completion and extension...
