Generation of Animated Stereo Panoramic Images for Image-Based Virtual Reality Systems [chapter]

Fay Huang, Chih-Kai Chang, Zi-Xuan Lin
2014 Lecture Notes in Computer Science  
The quality of the generated animated stereo panoramic image is satisfactory for virtual reality applications and the computation time is acceptable for practical use.  ...  In this paper, a novel approach is proposed for generating animated stereo panoramic images based on a single video sequence captured by a panning camera.  ...  Within the image displaying window, users are able to specify image regions containing undesired moving objects.  ...

2021 Visual Computing for Industry, Biomedicine, and Art  
In this article, light field imaging is reviewed from the following aspects with an emphasis on the achievements of the past five years: (1) depth estimation, (2) content editing, (3) image quality, (4  ...  ) scene reconstruction and view synthesis, and (5) industrial products because the technologies of lights fields also intersect with industrial applications.  ...  They used up to 4000 times fewer views and presented a plenoptic sampling framework by clearly specifying how users should sample input images for view synthesis with portable devices.  ...

Camus: Live Music Performance Using Camera Phones And Visual Grid Tracking

Michael Rohs, Georg Essl, Martin Roth
2006 Zenodo  
We demonstrate that mobile phones can be used as an actively oriented handheld musical performance device. To achieve this we use a visual tracking system of a camera phone.  ...  Mobile camera phones are widely available technology and we hope to find ways to make them into viable and widely used performance devices.  ...  (The camera image is not shown during normal use, since it distracts the user.)  ...
