چکیده

In trifocal transfer based novel view synthesis, matched pixels of both input views are projected in the novel view. The angle of view of this latest is usually narrow, i.e. the novel view is very close to input ones. In this paper we improve the method to get a large angle of view. A simplex approach is used to compute the model of the virtual views pose. This model allows the computation of the novel view at any desired angle of view. We also show that those results are very useful in micromanipulation tasks where transfer of edges is enough instead of the entire pixels of input views.

Novel View Specification and Synthesis

Given a set of real images, Novel View Synthesis (NVS) aims to produce views of a scene that would correspond to that of a virtual camera. There exist many approaches to solving this problem. We consider physically valid NVS methods, in particular those based on epipolar and trifocal transfer. We review a number of methods and place them into a common framework of view specification and mapping...

Estimation of and View Synthesis with the Trifocal Tensor

In this paper we propose a robust hierarchical approach for the estimation of the trifocal tensor. It makes use of pyramids, the sub-pixel Förstner point operator, least squares matching, RANSAC, and the Carlsson-Weinshall duality. We also show how the trifocal tensor can be utilized for an efficient view synthesis which we have optimized by parameterizing it according to the epipolar lines.

Trifocal motion modeling for object-based video compression and manipulation

Following a brief overview of two-dimensional (2-D) parametric motion models commonly used in video manipulation and compression, we introduce trifocal transfer, which is an image-based scene representation used in computer vision, as a motion compensation method that uses three frames at a time to implicitly capture camera/scene motion and scene depth. Trifocal transfer requires a trifocal ten...

From Images to Video: View Morphing of Three Images

This paper presents a novel image-based approach to generate a video of a scene based on only three wide-baseline uncalibrated images without the use of a 3D model. After automatically recovering an accurate trifocal plane amongst the original cameras, we compute the correct dense disparity maps between each rectified image pairs by using our feature-based trinocular-stereo algorithm. Employing...

Laser steering using virtual trifocal visual servoing

This paper focuses on the development of a weakly calibrated three-view based visual servoing control law applied to laser steering process. It proposes to revisit the conventional trifocal constraints governing a three-view geometry for a more suitable use in the design of an efficient trifocal vision-based control. Thereby, an explicit control law is derived, without any matrix inversion, whi...
