    We present a new system that applies an example-based learning method to learn facial motion patterns from a video sequence of individual facial behavior such as lip motion and facial expressions, and using that to create vivid three-dimensional (3-D) face animation according to the definition of MPEG-4 face animation parameters. The system consists of three key modules, face tracking, pattern lea... View full abstract»

    A light field is a collection of multiview images which represent a three-dimensional scene. Rendering from a light field provides a simple and efficient way to generate arbitrary new views of the scene, bypassing the difficult problem of acquiring accurate geometric and photometric models. The enormous amount of data required in a light field poses a key challenge in rendering. Tree-structured ve... View full abstract»

    One of the most difficult tasks in computer graphics is to enable virtual walkthroughs in very large and complicated environments that are photorealistic, seamless, and in real time. Current image-based rendering techniques, while capable of photorealism and interactive speeds, have failed in practice to extend to visualizations of such environments. We demonstrate an approach that defines a virtu... View full abstract»

    The creation of novel views using prestored images or image-based rendering has many potential applications, such as visual simulation, virtual reality, and telepresence, for which traditional computer graphics based on geometric modeling would be unsatisfactory particularly with very complex three-dimensional scenes. This paper presents a new image-based rendering system that tackles the two most... View full abstract»

  • Creating and encoding of cartoons using MPEG-4 BIFS: methods and results

    Our work focuses on the encoding of two-dimensional (2-D) graphics animated cartoons with MPEG-4. This stems from a need to stop encoding cartoons as videos and to start using methods more adapted to animated 2-D vector graphics sequences. We expected this could be an efficient coding with good versatility for various types of terminals. First, we present some technical specification for such cart... View full abstract»

    We survey the techniques for image-based rendering (IBR) and for compressing image-based representations. Unlike traditional three-dimensional (3-D) computer graphics, in which 3-D geometry of the scene is known, IBR techniques render novel views directly from input images. IBR techniques can be classified into three categories according to how much geometric information is used: rendering without... View full abstract»

    To store and transmit the large amount of image data necessary for Image-based Rendering (IBR), efficient coding schemes are required. This paper presents two different approaches which exploit three-dimensional scene geometry for multi-view compression. In texture-based coding, images are converted to view-dependent texture maps for compression. In model-aided predictive coding, scene geometry is... View full abstract»

  • Specialized hardware for deformable object modeling

    Deformable object modeling is a technology that will enable a broad range of new applications. Unfortunately, current techniques are far from being able to offer interactive performance for realistic scenes. We examine the idea of using low-cost highly specialized hardware in order to accelerate deformable object modeling. Details are presented regarding two generations of such experimental system...

    The image-based modeling and rendering (IBMR) approaches allow the time complexity of synthesizing novel images to be independent of scene complexity. Unfortunately, illumination control (relighting) is no longer trivial under the image-based framework. To relight the image-based scenery, the scene must be captured under various illumination conditions. This drastically increases the data volume. ... View full abstract»

    Image-based rendering (IBR) has become a very active research area in recent years. The spectral analysis problem for IBR has not been completely solved. In this paper, we present a new method to parameterize the problem, which is applicable for general-purpose IBR spectral analysis. We notice that any plenoptic function is generated by light ray emitted/reflected/refracted from the object surface... View full abstract»

    Terminal quality of service is the process of optimally scaling down the decoding and rendering computations to the available processing power, while maximizing the overall perceived quality. This process is applied in a real-time three-dimensional (3-D) decoding and rendering engine, exploiting scalable MPEG-4 coding algorithms. We derive a relation between the quality of the 3-D rendered objects... View full abstract»

    Generation and transmission of complex animation sequences can benefit substantially from the availability of tools for handling large amounts of data associated with dynamic three-dimensional (3-D) models. Previous works in 3-D dynamic compression consider only the simplest situation where the connectivity changes do not occur with time. In this paper, we present an approach for compressing 3-D d...
