“…More recently, the domain of time-varying representations has also been studied; image interpolation of the objects in dynamic scenes is investigated in [97] and [98]. Some of the interpolation methods could be used for applications in sports TV transmissions and can thus be regarded as a pioneering pseudo-3DTV application [99].…”

As a concluding remark, it can be argued that 3-D scene and texture representation techniques are mature enough to serve and fulfill the requirements of 3-D extraction, transmission and display sides in a 3DTV scenario.

Virtual Viewpoint Replay for a Soccer Match by View Interpolation From Multiple Cameras

Abstract-This paper presents a novel method for virtual view synthesis that allows viewers to virtually fly through real soccer scenes, which are captured by multiple cameras in a stadium. The proposed method generates images of arbitrary viewpoints by view interpolation of real camera images near the chosen viewpoints. In this method, cameras do not need to be strongly calibrated since projective geometry between cameras is employed for the interpolation. For avoiding the complex and unreliable process of 3-D recovery, object scenes are segmented into several regions according to the geometric property of the scene. Dense correspondence between real views, which is necessary for intermediate view generation, is automatically obtained by applying projective geometry to each region. By superimposing intermediate images for all regions, virtual views for the entire soccer scene are generated. The efforts for camera calibration are reduced and correspondence matching requires no manual operation; hence, the proposed method can be easily applied to dynamic events in a large space. An application for fly-through observations of soccer match replays is introduced along with the algorithm of view synthesis and experimental results. This is a new approach for providing arbitrary views of an entire dynamic event.Index Terms-Dynamic event, multiple cameras, projective geometry, soccer match, view interpolation, virtual view synthesis.

“…The concept of view morphing has also been extended to many other applications, such as, dynamic view interpolation [15], [16], [17], model based interactive view generation [18], image coding based on view rendering [19]. Weiskopf et al [20] propose an interesting application of image based rendering wherein the plenoptic function is appropriately modified to take care of relativistic aberration of light and search light effect to simulate a super-fast motion film.…”

Defocus morphing in real aperture images

We introduce a new concept called defocus morphing in real aperture images in this paper. View morphing is an existing example of shape preserving image morphing based on the motion cue. We prove that images can also be morphed based on the depth related defocus cue. This illustrates that the morphing operation is not necessarily a geometric process alone; one can also perform a photometry based morphing wherein the shape information is implicitly buried in the image intensity field. A theoretical understanding of the defocus morphing process has been presented in this paper. Mathematically we show that, given two observations of a 3D scene for different camera parameter settings, we can obtain a virtual observation for any camera parameter setting through a simple nonlinear combination of these observations.
