Multi-scale deep-learning approaches for visual coding and processing
Visual information can be captured in both 2D and 3D formats. For example, an image is a 2D representation while a point cloud is a 3D representation. A sequence of images captured to represent a certain duration of an event is called a video. Similarly, such a sequence of a point cloud is called a …

"""Travelling Without Moving"": A Study on the Reconstruction, Compression, and Rendering of Three-Dimensional Environments for Telepresence"
… we study issues related to free-view 3D-video, and in particular issues of 3D scene reconstruction, compression, and rendering. We present four main contributions. First, we present a novel algorithm which performs surface reconstruction from planar arrays of cameras and generates …

Omnidirectional view and multi-modal streaming in 3D tele-immersion system
3D Tele-immersion (3DTI) technology allows full-body, multi-modal content delivery among geographically dispersed users. In 3DTI, user’s 3D model will be captured by multiple RGB-D (color plus depth) cameras surround- ing user’s body. In addition, various sensors (e.g., motion sensors, medical …

Image Segmentation and Range Estimation Using a Moving-aperture Lens
… to an image sequence, captured using a video camera with a moving aperture lens. For a stationary scene, optical flow magnitudes and direction are directly related to the three-dimensional object distance and location from the observer. Exploiting this information, we have successfully …

Audiovisual spatial congruence, and applications to 3D sound and stereoscopic video
While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant …

Unsupervised video segmentation and its application to activity recognition
… temporal information to achieve consistent 3D video segmentation. By exploiting non-local structure in both spatial and temporal space, the instabilities of the segmented regions were alleviated. A segmentation tree was built within every frame, and the label consistency was enforced within …

An Activity-Based Framework for Automated Placement and Configuration of Multiple Stereo Cameras
… The integration can be achieved by real-time 3D imaging at several geographically distributed locations followed by fusion of information from multiple virtual and physical spaces. Systems that enable such information fusions are called tele-immersive and need to be easily deployed at many …

Human-centric control of video functions and underlying resources in 3D tele-immersive systems
3D tele-immersion (3DTI) has the potential of enabling virtual-reality-like interaction among remote people with real-time 3D video. However, today's 3DTI systems still suffer from various performance issues, limiting their broader deployment, due to the enormous demand on temporal (computing) and …

Efficient data structures for piecewise-smooth video processing
A number of useful image and video processing techniques, ranging from low level operations such as denoising and detail enhancement to higher level methods such as object manipulation and special effects, rely on piecewise-smooth functions computed from the input data. In this thesis, we present …

Three-Dimensional Imaging using a Novel Rotating Point Spread Function Imager
<p>The capability to achieve three-dimensional (3D) imaging in a single snapshot is a highly coveted goal for the imaging community. To be able to extend the depth-of-field while simultaneously encoding depth in the point spread function (PSF) itself allows an imaging solution which is less time …

Computer Generation of Integral Images using Interpolative Shading Techniques
Research to produce artificial 3D images that duplicates the human stereovision has been ongoing for hundreds of years. What has taken millions of years to evolve in humans is proving elusive even for present day technological advancements. The difficulties are compounded when real-time generation …
