For broadcasting purposes MIXED REALITY, the combination of real and virtual scene content, has become ubiquitous nowadays. Mixed Reality recording still requires expensive studio setups and is often limited to simple color keying. We present a system for Mixed Reality applications which uses depth keying and provides threedimensional mixing of real and artificial content. It features enhanced ...

Dynamic depth recovery from unsynchronized video streams is an open problem. In this paper, we propose a novel framework for estimating dense depth information of dynamic scenes using multiple video streams captured from unsynchronized stationary cameras. The main idea is to convert the unsynchronized depth computation problem to the traditional synchronized depth computation problem in which m...

Visual odometry can be augmented by depth information such as provided by RGB-D cameras, or from lidars associated with cameras. However, such depth information can be limited by the sensors, leaving large areas in the visual images where depth is unavailable. Here, we propose a method to utilize the depth, even if sparsely available, in recovery of camera motion. In addition, the method utiliz...

The idea of augmenting our physical reality with virtual entities in an unobtrusive, embedded way, i. e., without the necessity of wearing hardware or using expensive display devices is exciting. Due to the development of new inexpensive depth camera systems an implementation of this idea became affordable for everyone. This paper demonstrates an approach to capture and track a head using a dep...

The main motivation behind this thesis was to create a new method of interaction between the physical and virtual space. The object was set to be achieved by creating a 3D-scanner capable of producing 360-degrees scans of real world objects to be visualized and used inside virtual spaces. The implementation of this objective began by conducting a background research about the existing methods f...

We have developed high-speed and high-resolution spectral domain optical coherence tomography at 1.3 µm using an InGaAs line-scan camera and a broadband light source with the bandwidth of 170 nm that produces a theoretical axial resolution of 4.4 µm in air. We compared axial resolutions from point spread functions (PSFs) and depth ranges while changing the full spectral bandwidth detected by th...

Laparoscopic surgical training systems limit the users' depth perception and hand-eye coordination due to the use of a 2D camera image. In this paper, we present an approach to enhance visualization using augmented reality which aids in hand-eye coordination and depth perception in the operating environment. An optimal path is calculated in a 3D space and projected onto a 2D camera image. The m...

Inferring the depth and shape of remote objects and the complete camera motion from a sequence of images is possible in principle, but is an ill-conditioned problem, because translation and rotation are hard to distinguish, and the size of the object is small with respect to its distance from the camera. We show how to overcome these problems by inferring shape and rotation without computing de...
