    We address the problem of object class segmentation of 3D point clouds. Each point of a cloud should be assigned a class label determined by the category of the object it belongs to. Non-associative Markov networks have been applied to this task recently. Indeed, they impose more flexible constraints on segmentation results in contrast to the associative ones. We show how to train non-associative ... View full abstract»

  • Toward Automatic 3D Generic Object Modeling from One Single Image

    Publication Year: 2011, Page(s):9 - 16
    Cited by:  Papers (3)
    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1716 KB) | HTML iconHTML

    We present a novel method for solving the challenging problem of generating 3D models of generic object categories from just one single un-calibrated image. Our method leverages the algorithm proposed in [1] which enables a partial reconstruction of the object from a single view. A full reconstruction is achieved in a subsequent object completion stage where modified or state-of-the-art 3D shape a... View full abstract»

    Multi-view photometric stereo is well established for the shape recovery of static objects. However, it is difficult to align motion images under varying illumination so as to perform photometric stereo reconstruction for dynamic objects. To tackle this issue, this paper presents an optical flow estimation approach which works under periodically varying illuminations, and in cooperation with photo... View full abstract»

  • Surface Reconstruction in Photometric Stereo with Calibration Error

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (1677 KB) | HTML iconHTML

    A method is described for surface reconstruction that accounts for the calibration errors in photometric stereo. The angular errors in calibrated light directions due to noise cause errors in surface normal estimates. Investigation of the effect of these calibration errors on the surface normals revealed that errors in the estimated light directions and in the surface normal estimates follow a Fis...

    Virtual representations of real world areas are increasingly being employed in a variety of different applications such as urban planning, personnel training, simulations, etc. Despite the increasing demand for such realistic 3D representations, it still remains a very hard and often manual process. In this paper, we address the problem of creating photo realistic 3D scene models for large-scale a... View full abstract»

  • Pseudo-Immersive Real-Time Display of 3D Scenes on Mobile Devices

    The display of complex 3D scenes in real-time on mobile devices is difficult due to the insufficient data throughput and a relatively weak graphics performance. Hence, we propose a client-server system, where the processing of the complex scene is performed on a server and the resulting data is streamed to the mobile device. In order to cope with low transmission bit rates, the server sends new da... View full abstract»

  • A System for Capturing Textured 3D Shapes Based on One-Shot Grid Pattern with Multi-band Camera and Infrared Projector

    Recently, several method have been proposed to capture 3D shapes of a moving object at a high frame rate. One of promising approach to reconstruct a 3D shape is a projector-camera system that projects structured light pattern. One of the problem of this approach is that it has difficulty to obtain texture simultaneously because the texture is interfered by the illumination from the projector. The ... View full abstract»

    Stereo vision systems for 3D reconstruction have been deeply studied and are nowadays capable to provide a reasonably accurate estimate of the 3D geometry of a framed scene. They are commonly used to merely extract the 3D structure of the scene. However, a great variety of applications is not interested in the geometry itself, but rather in scene analysis operations, among which scene segmentation... View full abstract»

    We present a novel scalable framework for free-form object classification in range images. The framework includes an automatic 3D object recognition system in range images and a scalable database structure to learn new instances and new categories efficiently. We adopt the TAX model, previously proposed for un-supervised object modeling in 2D images, to construct our hierarchical model of object c... View full abstract»

    This paper presents a real-time stereo algorithm that estimates scene depth information with high accuracy. Our algorithm consists of two novel components. First, we apply a modified two-pass aggregation to the adaptive cost aggregation process, use color similarity to calculate support weight, and introduce a credibility estimation mechanism to reduce accuracy loss during two-pass aggregation. Se... View full abstract»

    In this paper, a novel variant of the ICP algorithm is proposed for registration of partially overlapping range images. Biunique correspondence is introduced to enhance the performance of ICP by searching multiple closest points. A new kind of outlier is defined, called No-Correspondence (NC) Outlier, which is the point that is not assigned to a biunique correspondence. In order to maintain effici... View full abstract»

    In this paper, we present an efficient technique for generating multi-perspective panoramic images of long scenes. The input to our system is a video sequence captured by a moving camera navigating through a long scene, and our goal is to efficiently generate a panoramic summary of the scene. This problem has received considerable attention in recent years, leading to the development of a number o... View full abstract»

    We present a novel discriminative appearance model for monocular multi-target tracking and segmentation in a comparatively crowded scene. Based on the hypothesis that the discriminability among different targets plays an important role in improving the tracking performance, we choose different feature spaces for every target in the scene to insure the discriminability from other targets. In order ... View full abstract»

    We introduce a new enhancement to speed up the physical mass-spring model for efficient cloth simulation. The mass-spring model is known for its accuracy but slowness. The proposed technique tackles the computation burden of the model by developing a linearization solution for the bending function. The proposed technique is about six times faster than the traditional technique of directly evaluati... View full abstract»

    We describe a structured light phase measuring triangulation technique extending the conventional four-step phase shift sequence with embedded information suited to assist the phase unwrapping process. Using the embedded information, we perform automatic phase unwrapping in the presence of discontinuous or isolated surfaces without extending the length of the phase shift sequence or requiring ster...
