  • An Interactive Warping Method for Multi-channel VR Projection Display Systems with Quadric Surface Screens

    Publication Year: 2013, Page(s):1 - 8
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (849 KB) | HTML iconHTML

    In this paper, we present a practical non-camera-based interactive warping method for multi-channel immersive VR projection display systems with quadric surface screens. Instead of using one or multiple cameras as most previous methods did, we employ a commercial theodolite and a mouse to interactively calibrate each projector on site. By taking advantage of the nature of shape of the curved scree... View full abstract»

  • Saliency-Guided Luminance Enhancement for 3D Shape Depiction

    Publication Year: 2013, Page(s):9 - 14
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1412 KB) | HTML iconHTML

    We present a novel saliency-guided shading scheme for 3D shape depiction incorporating the mesh saliency into luminance enhancement in this paper. Using a distanced-based mesh saliency computation, we propose a new perceptual-saliency measure which can depict surface salient regions. Due to the visual salient regions, we emphasize the details and the overall shape of models by locally enhancing th... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1013 KB) | HTML iconHTML

    For the integrated motor propulsor, numerical model which integrated the internal and external flow field was established. Computational region discretization was carried out through using high quality multi-block structure grid based on CFD method. The flow field performance was calculated by adopting Reynolds time averaged method, and the steady hydrodynamic calculation was sealed off by using t... View full abstract»

    Image-based modeling problem is a tough and basic problem in computer vision and computer graphics. This paper provides an improved solution to generate a scene model from a single image based on the multi-scale Markov random field. We consider the different influence of the different color components in RGB color space when modeling through a single still image. In this paper, we proposed a weigh... View full abstract»

    In remote visualization for complex 3D dynamic datasets, existing vertex compression algorithms have low compression factor, and compressed datasets cannot be transmitted to client in once if its size is bigger than bandwidth. In order to solve these problems, this paper presents a compact impression for 3D dynamic datasets in certain range. We construct an equilateral triangle to obtain and compr... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (933 KB) | HTML iconHTML

    This paper develops a laser sheet scanning based technique for capturing and reconstructing sequential volumetric models of smoke. First, a dedicated setup is introduced as the laser sheet illuminator in horizontal scanning. To achieve an accurate acquisition, a signal synchronized scheme is added between the galvanometer and the high-speed camera. Then, with a laser sheet sweeping through the vol... View full abstract»

    A new fast divide and conquer ray tracing algorithm based on BVH partition which can remove unnecessary rays in subspace is proposed to resolve the problem that bounding boxes not tightly surround the primitives by space divide scheme which then increased unnecessary rays in subspace. Its core idea is that using Bin based BVH construction algorithm to partition primitives into two parts then distr... View full abstract»

  • Variational Formulation and Multilayer Graph Based Color-Texture Image Segmentation in Multiphase

    Publication Year: 2013, Page(s):56 - 63
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (634 KB) | HTML iconHTML

    A variational segmentation approach of color-texture images is proposed in this lecture. To improve the description ability, we use our proposed color-texture descriptor in [1] to describe color-texture. Due to heterogeneous image objects and nonlinear variation exist in color-texture image, it is not appropriate to use one single/multiple constant in Chan and Vese model for describing each phase ...

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (948 KB) | HTML iconHTML

    We propose a new efficient technique for acquiring normal maps of nearly flat objects using a flatbed scanner. The technique requires no hardware modification or dedicated calibration. Our setup consists of a conventional flatbed scanner and a clamp on which a planar checkerboard is glued. We take four scans of the object manually rotated by roughly 90 degrees. The scans are then registered by sub... View full abstract»

    To continuously track the multiple occluded object in the crowded scene, we propose a new multi-view multi-object tracking method basing on artificial potential field and cooperative particle filter in which we combine the bottom-up and top-down tracking methods for better tracking results. After obtaining the accurate occupancy map through the multi-planar consistent constraint, we predict the tr... View full abstract»

    Height field and grid data are frequently updated during simulation of large scale ocean water, which reduces the frame rates of whole virtual scene. A CUDA-based framework for unbounded real-time ocean rendering is proposed in this paper. Firstly, height field data is calculated on GPU using FFT method. Then the whole view frustum dependent dynamic grid is created by an adaptive algorithm with co... View full abstract»

    This paper proposes a novel method to complete the missing appearance of mesh surfaces through structure propagation and texture matching. In advance, the appearance on surfaces is divided into structure and texture components. First, the missing structures are predicted through structure propagation. The structure propagation is guided by surfaces geometric features by using 3D tensor voting and ... View full abstract»
