DEPTH ESTIMATION IN LIGHT FIELD CAMERA ARRAYS BASED ON MULTI-STEREO MATCHING AND BELIEF PROPAGATION
Despite of the rich variety of depth estimation methods in the literature, computing accurate depth in multi-view camera systems remains a difficult computer vision problem. The paper proposes a novel depth estimation method for light field...
3D OBJECTIVE QUALITY ASSESSMENT OF LIGHT FIELD VIDEO FRAMES
With the rapid advances in light field displays and cameras, research in light field content creation, visualization, coding and quality assessment is now beyond a state of emergence; it has already emerged and started attracting a signific...
EXPERT EVALUATION OF A NOVEL LIGHT-FIELD VISUALIZATION FORMAT
Light-field visualization is continuously emerging in industrial sectors, and the appearance on the consumer market is approaching. Yet this process is halted, or at least slowed down, by the lack of proper display-independent light-field f...
SIMULATION OF PLENOPTIC CAMERAS
Plenoptic cameras enable the capturing of spatial as well as angular color information which can be used for various applications among which are image refocusing and depth calculations. However, these cameras are expensive and research in ...
ACCURATE METHOD OF TEMPORAL-SHIFT ESTIMATION FOR 3D VIDEO
Video synchronization is a fundamental computer-vision task that is necessary for a wide range of applications. A 3D video involves two streams, which show the scene from different angles concurrently, but many cases exhibit desynchronizati...
DYNAMIC FRACTURING OF 3D MODELS FOR REAL TIME COMPUTER GRAPHICS
This work proposes a method of fracturing one-sided 3D objects, in real time, using standard GPU shaders. Existing implementations include either pre-fracturing objects and replacing them at run-time, or precomputing the fracture patterns a...
ADAPTIVE COLOR CORRECTION IN VIRTUAL VIEW SYNTHESIS
In the paper an adaptive color correction method for virtual view synthesis is presented. It deals with the typical problem in free navigation systems - different illumination in views captured by different cameras acquiring the scene. The ...
ICP WITH DEPTH COMPENSATION FOR CALIBRATION OF MULTIPLE TOF SENSORS
We propose an iterative closest point (ICP) based calibration for time of flight (ToF) multiple depth sensors. For the multiple sensor calibrations, we usually use 2D patterns calibration with IR images. The depth sensor output depends on c...
A NOVEL DISPARITY-ASSISTED BLOCK MATCHING-BASED APPROACH FOR SUPER-RESOLUTION OF LIGHT FIELD IMAGES
Currently, available plenoptic imaging technology has limited resolution. That makes it challenging to use this technology in applications, where sharpness is essential, such as film industry. Previous attempts aimed at enhancing the spatia...
LATEST RESEARCH AT THE ADVANCED DISPLAYS LABORATORY AT NTU
There are many basic ways of providing a glasses-free 3D display and the three methods considered most likely to succeed commercially were chosen for our current research, these are; multi-layer light field, head tracked and super multiview...
