In this paper, a novel closed-form transformation estimation method based on feature guided moving least squares together with manifold regularization is proposed for nonrigid image/surface deformation. The method takes the user-controlled point-offset-vectors and the feature points of the image/surface as input, and estimates the spatial transformation between the two control point sets for each...
High resolution depth-maps, obtained by upsampling sparse range data from a 3D-LIDAR, find applications in many fields ranging from sensory perception to semantic segmentation and object detection. Upsampling is often based on combining data from a monocular camera to compensate the low-resolution of a LIDAR. This paper, on the other hand, introduces a novel framework to obtain dense depth-map solely...
The rise in global temperature accelerates the melting of the ice sheets. This highlights the importance of understanding the ice sheet structure and dynamics. Although fundamental for a reliable 3D modeling of the ice subsurface, the development of automatic techniques for the integration of multisensor data acquired over the ice sheets is still very limited. To address this issue, in this paper...
To extract a tubular object boundary from a volumetric image is important to compute its morphometric properties, like the estimation of the boundary curvature, or the radius of a tubular object, for example, the radius is one of the descriptions of blood vessel for detecting the soft plaque. How to estimate the gradient of the volumetric data has an influence on the computation results of the morphometric...
The generation of three-dimensional (3D) videos from monoscopic two-dimensional (2D) videos has received a lot of attention in the last few years. Current conversion techniques are based on generating an estimated depth map for each frame from different depth cues, and then using Depth Image Based Rendering (DIBR) to synthesize the additional views. Efficient interactive techniques have been developed...
The data registration transforms multiple datasets into the same coordinate system, and in this way overlapping components of these sets are aligned. The registration is the fundamental of many advanced tasks, such as data fusion. There are plenty of solutions to data registration, and among them the algorithms based on Fourier analysis are efficient for large offsets but intricate. The surveys about...
This paper presents an efficient view synthesis distortion estimation method for 3-D video. It also introduces the application of this method to Advanced Video Coding (AVC)- and High Efficiency Video Coding (HEVC)-compatible 3-D video coding. Although the proposed view synthesis distortion scheme is generic, its use for actual 3-D video codec systems addresses the many issues caused by different video-coding...
Estimating depth in monoscopic images and videos is a non-trivial problem due to the inherent ambiguity that arises when a 3D scene is projected onto a 2D plane (the image). But because depth estimation is so useful, many different techniques have been developed to solve this problem. Unfortunately these methods tend to be computationally intensive or require precise knowledge about the camera that...
For the purpose of this paper we group, under the generic term multiview video, different systems for which multiple standard video cameras and, possibly, additional depth-capturing cameras, are used. Video is then presented to the user using special glasses or displays. Research work in this area has focused on topics ranging from designing compression techniques to developing new 3D displays. In...
Virtual view synthesis is an important technique for multi-view 3D display. This makes that multi-view images for 3D display can be created by only two-view images. An efficient virtual view synthesis method was proposed based on disparity map and image interpolation. An adaptive weight stereo matching approach was adopted to obtain the initial disparity map. Cross-checking technique was utilized...
In this paper, a real-time augmented view synthesis system is proposed. With real-time consideration and augmented reality property, the proposed system provides a novel application for making car pillars transparent to enlarge the eyesight of the drivers. Thanks to the proposed trinocular depth estimation, online depth generation becomes possible through trinocular fast dense disparity estimation...
