“…Those techniques proceed in general in 3 stages [1,2]: the estimation of correspondences between the novel and the reference views, the estimation of the contribution (or weight) of each view in the final view, and the rendering method. The stereo correspondence estimation problem has been largely explored [3], but few works have formally studied which is the correct leverage between the contributions of each view.…”

We address the topic of novel view synthesis from a stereoscopic pair of images. Most current techniques are composed of 3 stages: reconstruction of correspondences between the views, estimation of the per-pixel or per-image weight of each view in the final view, and rendering. Rendering methods can be classified into direct methods, which define the final image as a function of the original images, and variational methods, where the synthesized image is expressed as the solution minimising an energy. The existing literature is mainly focused on the correspondence issue, but few publications address the questions of which weights or blending factors are better, or which rendering method should be used. In this paper, we experiment different combinations of blending factors and rendering methods, in order to evaluate the influence of these two factors on the final image quality.Index Terms-Viewpoint interpolation, image-based rendering, blending factors, variational method.

“…Targeting the same application, Devernay et al [5] proposed a disparity-remapping scheme that does not distort objects with respect to perceived depth. To aid the stereographer with the capture on the set, Zilly et al [29] presented the Stereoscopic analyzer, a tool for online validation of stereoscopic capture, including image rectification, detection of window violations, and optimal interocular distance proposal.…”

We present a detailed blueprint of our stereoscopic freeviewpoint video system.Using unsynchronized footage as input, we can render virtual camera paths in the post-production stage.The movement of the virtual camera also extends to the temporal domain, so that slow-motion and freeze-and-rotate shots are possible. As a proof-of-concept, a full length stereoscopic HD music video has been produced using our approach.

“…3D cinema and 3DTV correspond to different screen sizes and viewing distances. When the same stereoscopic-3D content is viewed on a cinema screen and 3DTV screen, it will produce a different 3D impression (with regards to apparent depth and roundness of objects) [1]. This implies that the 3D content must be captured for a specific viewing geometry, i.e., the targeted screen size and viewing distance, in order to provide a satisfactory 3D experience.…”

3D cinema and 3DTV are at two different levels in the screen size spectrum. When the same stereoscopic-3D content is viewed on a cinema screen and 3DTV screen, it will produce a different 3D impression. As a result, it is difficult to fulfill the requirements of 3DTV with content captured for 3D cinema. Thus, it is important to properly address the issue of 3DTV content creation to avoid possible delays in the deployment of 3DTV. In this paper, we first explore the effects of using the same content for 3D cinema and 3DTV and then analyze the performance of several disparity based transformations for 3D cinema to 3DTV content conversion, by subjective testing. Effectiveness of the transformations is analyzed in terms of both depth quality and visual comfort of 3D experience. We show that by using a simple shift-based disparity transformation technique, it is possible to enhance the 3DTV experience from a common input signal which is originally captured for cinema viewing.
