Abstract [en]

In this paper we propose a novel approach for 3D video/photo visualization using an ordinary digital camera. The idea is to turn any 2D camera into 3D based on the data derived from a collection of captured photos or a recorded video. For a given monocular input, the retrieved information from the overlapping photos can be used to provide required information for performing 3D output. Robust feature detection and matching between images is hired to find the transformation between overlapping frames. The transformation matrix will map images to the same horizontal baseline. Afterwards, the projected images will be adjusted to the stereoscopic model. Finally, stereo views will be coded into 3D channels for visualization. This approach enables us making 3D output using randomly taken photos of a scene or a recorded video. Our system receives 2D monocular input and provides double layer coded 3D output. Depending on the coding technology different low cost 3D glasses will be used for viewers.

Abstract [en]

The rapid development of mobile devices during the recent decade has been greatly driven by interaction and visualization technologies. Although touchscreens have signicantly enhanced the interaction technology, it is predictable that with the future mobile devices, e.g., augmentedreality glasses and smart watches, users will demand more intuitive in-puts such as free-hand interaction in 3D space. Specically, for manipulation of the digital content in augmented environments, 3D hand/body gestures will be extremely required. Therefore, 3D gesture recognition and tracking are highly desired features for interaction design in future smart environments. Due to the complexity of the hand/body motions, and limitations of mobile devices in expensive computations, 3D gesture analysis is still an extremely diffcult problem to solve.

This thesis aims to introduce new concepts, theories and technologies for natural and intuitive interaction in future augmented environments. Contributions of this thesis support the concept of bare-hand 3D gestural interaction and interactive visualization on future smart devices. The introduced technical solutions enable an e ective interaction in the 3D space around the smart device. High accuracy and robust 3D motion analysis of the hand/body gestures is performed to facilitate the 3D interaction in various application scenarios. The proposed technologies enable users to control, manipulate, and organize the digital content in 3D space.
