Depth-Image-Based Rendering (DIBR) is a technique which utilizes 2D texture images and corresponding depth maps to synthesize stereoscopic views. However, it could introduce the hole artifacts that heavily degrades the rendered quality of 3D video. In this paper, a content-adaptive Depth-Video-Based Rendering (DVBR) method is proposed to eliminate the hole artifacts that are caused by quantization...
Digital video segmentation is an active area of research. Generally, the significances of this segmentation mask can be explained as follows: Firstly, the mask can be used for image examining, editing, compression, analysis and understanding. Secondly, the virtual reality system can use the panorama and mask to appear the virtual 3-D environment. So the research of such an efficient video segmentation...
Digital image mosaic is an active area of research. Generally, the significances of this synthetic panorama can be explained as follows: Firstly, increasing the angle of the optics system view. Secondly, the panorama can be used for image examining, editing, analysis and understanding. Thirdly, the virtual reality system can use the panorama to appear the virtual 3-D environment. So the research of...
Digital image mosaic can be defined as image registration and fusion of lots of overlapping digital images or multiple video frames into a single wide field of view image or dynamic panoramic image. It is brought for the limitation of camera visual angle, which is impossible to shoot a panorama image once. So the research of such a robust mosaic panorama technique for video is necessary and possible...
Algorithms to reliably and accurately extract inter-strip motion are crucial for motion artifacts suppression in PROPELLER MRI. The current algorithm is based on image registration through maximizing correlation coefficients of k-space data. To decouple rotational and translational estimation, only magnitude of k-space data is taken into account while performing rotational estimation. Because little...
