    Segmentation of images into foreground (an actor) and background is required for many motion picture special effects. To produce these shots, the unwanted background must be removed so that none of it appears in the final composite shot. The standard approach requires the background to be a blue screen. Systems that are capable of segmenting actors from more natural backgrounds have been proposed,... View full abstract»

  • Shadow-aware object-based video processing

    Local illumination changes due to shadows often reduce the quality of object-based video composition and mislead object recognition. This problem makes shadow detection a desirable tool for a wide range of applications, such as video production and visual surveillance. In this paper, an algorithm for the isolation of video objects from the local illumination changes they generate in real world seq... View full abstract»

  • Automated rig removal with Bayesian motion interpolation

    Publication Year: 2005, Page(s):407 - 414

    Some of the most convincing film and video effects are created in digital post-production by removing apparatus that supports or manipulates actors and objects. Wires, cranes and other objects can be removed by digitally painting them out of the scene provided that some 'clean plate' image is available for pasting in the missing regions. The problem of when no such plate is available is addressed.... View full abstract»

  • Affine motion compensation using a content-based mesh

    Publication Year: 2005, Page(s):415 - 423
    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2097 KB)

    A content-based approach to the design of a triangular mesh is presented, and its application to affine motion compensation is investigated. An image is first segmented into moving objects, which are then approximated with polygons. Then, a triangular mesh is generated within each polygon, thus ensuring that no triangle straddles multiple regions. Translation and affine motion parameters are deter... View full abstract»

  • Techniques for automated reverse storyboarding

    Publication Year: 2005, Page(s):425 - 436
    Cited by:  Papers (7)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1796 KB)

    Storyboarding is a standard method for visual summarisation of shots in film and video preproduction. Reverse storyboarding is the generation of similar visualisations from existing footage. The key attributes of preproduction storyboards are identified, then computational techniques that extract corresponding features from video, render them appropriately, and composite them into a single storybo...

  • Automated camerawork for capturing desktop presentations

    Publication Year: 2005, Page(s):437 - 447
    Cited by:  Papers (3)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1006 KB)

    A novel automated camera control method for capturing desktop presentations is introduced. Typical features and the camerawork of shots that appear frequently in TV programs are discussed. To realise those features in this automated video capturing system, the purpose of camerawork is classified from two points of view: target and aspect-of-target. Then, the correspondence between the classificati... View full abstract»

  • Real-time video effects on a PlayStation2

    Publication Year: 2005, Page(s):448 - 453
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (306 KB)

    The Sony PlayStation2 (PS2), with its powerful rendering and vector processing capabilities, built-in MPEG decoder, and large capacity hard disc drive (HDD), possesses fundamental assets that make it an ideal platform for processing video. Research carried out at Sony BPRL, where we have extensive experience of video effects processing, has shown that this inexpensive games console can, in fact, c... View full abstract»

    The goal of the EC-funded IST project ORIGAMI was the development of advanced tools and new production techniques for high-quality and seamless integration of real and virtual content in film and TV productions. In particular, the project focused on pre-production tools for automatic virtual set creation through image-based 3-D modelling of environments and objects. One key goal of the project was...

  • Image-based rendering of complex scenes from a multi-camera rig

    Publication Year: 2005, Page(s):470 - 480
    Cited by:  Papers (3)  |  Patents (6)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2147 KB)

    Image-based rendering is a method to synthesise novel views from a set of given real images. Two methods to extrapolate novel views of complex scenes with occlusions and large depth discontinuities from images of a moving uncalibrated multi-camera rig are described. The real camera viewpoints are calibrated from the image data and dense depth maps are estimated for each real view. Novel views are ... View full abstract»

  • 3D studio production of animated actor models

    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (1252 KB)

    A framework for constructing detailed animated models of an actor's shape and appearance from multiple view images is presented. Multiple views of an actor are captured in a studio with controlled illumination and background. An initial low-resolution approximation of the person's shape is reconstructed by deformation of a generic humanoid model to fit the visual hull using shape constrained optim... View full abstract»

    Cited by:  Papers (2)
    IEEE is not the copyright holder of this material | Click to expandAbstract | PDF file iconPDF (2002 KB)

    An efficient system for realistic speech animation is proposed. The system supports all steps of the animation pipeline, from the capture or design of 3D head models up to the synthesis and editing of the performance. This pipeline is fully 3D, which yields high flexibility in the use of the animated character. Real detailed 3D face dynamics, observed at video frame rate for thousands of points on...

    The main challenge of tracking articulated structures like hands is their many degrees of freedom (DOFs). A realistic 3-D model of the human hand has at least 26 DOFs. The arsenal of tracking approaches that can track such structures fast and reliably is still very small. This paper proposes a tracker based on stochastic meta-descent (SMD) for optimisations in such high-dimensional state spaces. T... View full abstract»
