Several authors have recently investigated the ability to compute intermediate views of a scene using given 2D images from arbitrary camera positions. The methods fall under the topic of image bused rendering. In the case we give here, linear morphing between two parallel views of a scene produces intermediate views that would have been produced by parallel movement of a camera. Hence, the tech...

An important aim of immersive teleconferencing systems is to create realistic 3D virtual views of remote conferees. Hence, systems should be able to deal with hand gestures as well as occluded areas in reference images required in derived views. The quality of such derived views is dependent not only on the analysis and synthesis process but also the multiview camera set-up. Often the popular c...

We show a simple and efficient way for rendering arbitrary views from so-called free-form light fields, employing a convex free form camera surface and a set of arbitrarily oriented camera planes. This way directionally varying real-world imagery can be displayed without intermediate resampling steps, and yet rendering of free form light fields can be performed as efficiently as for two-planepa...

In this paper we propose a post-processing pipeline to recover accurately the views (light-field) from the raw data of a plenoptic camera such as Lytro and to estimate disparity maps in a novel way from such a light-field. First, the microlens centers are estimated and then the raw image is demultiplexed without demosaicking it beforehand. Then, we present a new block-matching algorithm to esti...

Multiple view projection holography is a method to obtain a digital hologram by recording different views of a 3D scene with a conventional digital camera. Those views are digitally manipulated in order to create the digital hologram. The method requires a simple setup and operates under white light illuminating conditions. The multiple views are often generated by a camera translation, which u...

Multiple views of a rigid 3D scene captured from a moving camera can be used to estimate the 3D poses (rotations and translations) and the 3D structure of the unmodeled scene. In this problem domain, there are two key problems addressed in this paper: (i) automatic Euclidean pose estimation in extended sequences even when views of the scene rapidly change, that is features come in and go out of...

We present new test results for our active object recognition algorithms. The algorithms are used to classify and estimate the pose of objects in di erent stable rest positions and automatically re-position the camera if the class or pose of an object is ambiguous in a given image. Multiple object views are now used in determining both the nal object class and pose estimate; previously, multipl...

In this paper the GPU implementation of a real-time isosurface volume-rendering system is described in detail, which aims at autostereoscopic displays. Since autostereoscopic displays provide images for many views, and thus require different camera settings in each pixel, and even in the three color channels of a pixel, naive rendering approaches would slow down the rendering process by a facto...

We propose a method of gait identification based on multiview gait images using an omnidirectional camera. We first transform omnidirectional silhouette images intopanoramic ones and obtain a spatiotemporal Gait Silhouette Volume (GSV). Next, we extract frequencydomain features by Fourier analysis based on gait periods estimated by autocorrelation of the GSVs. Because the omnidirectional camera...

We introduce the problem of view interpolation for dynamic scenes. Our solution to this problem extends the concept of view morphing 11] and retains the practical advantages of that method. We are specii-cally concerned with interpolating between two reference views captured at diierent times, so that there is a missing interval of time between when the views were taken. The synthetic interpola...
