3D object reconstruction using light-field information

Semester: 

N/A

Offered: 

2011

We proposed a reconstruction method for the occluded region of three-dimensional (3D) object using the depth extraction based on the optical flow and triangular mesh reconstruction in integral imaging. The depth information of sub-images from the acquired elemental image set is extracted using the optical flow with sub-pixel accuracy, which alleviates the depth quantization...

2D/3D convertible and 360°-viewable integral Imaging (light-field display) using electroluminescent film

Semester: 

N/A

 

We propose a thin and compact integral imaging system using electroluminescent (EL) films as backlight. EL film has the advantage that it can operate continuously even when it is cut or punctured. Using this characteristic, we generate an array of pinholes on EL film to form a point light-source array for reconstructing...

Effect of fundamental depth resolution and cardboard effect to perceived depth resolution on multi-view display

Semester: 

N/A

 

In three-dimensional television (3D TV) broadcasting, we find the effect of fundamental depth resolution and the cardboard effect to the perceived depth resolution on multi-view display is important. The observer distance and the specification of multi-view display quantize the expressible depth range, which affect the perception of depth resolution of the observer. In addition, the multi-view 3D TV needs the view synthesis process using depth image-based rendering which...
