In this paper, we present a practical vision based Simultane-ous Localization and Mapping (SLAM) system for a highly dynamic environment. We adopt a multibody Structure from Motion (SfM) approach, which is the generalization of classical... more
ToF cameras are new instruments based on CCD/CMOS sensors which measure distances instead of radiometry. The resulting point clouds show the same properties (both in terms of accuracy and resolution) of the point clouds acquired by means... more
In this work, the integration between data provided by Time-of- light cameras and a multi-image matching technique for metric surveys of architectural elements is presented. The main advantage is given by the quickness in the data... more
The aim of this study is to build a Web-based virtual tour system, focused at the presentation of archaeological sites. The proposed approach is comprised of powerful techniques such as multiview 3D reconstruction, omnidirectional viewing... more
Image segmentation has traditionally been thought of us a low/mid-level vision process incorporating no high level constraints. However, in complex and uncontrolled environments, such bottom-up strategies have drawbacks that lead to large... more
In Thailand, there are several types of (tangible) cultural heritages. This work focuses on 3D modeling of the heritage objects from multi-views images. The images are acquired by using a DSLR camera which costs around $1,500 (camera and... more
Different institutions worldwide, such as economic, social and political, are relying increasingly on the communication technology to perform a variety of functions: holding remote business meetings, discussing design issues in product... more
... Camera calibration is the first step towards computational computer vision. ... light emitter) permits crossing both optical rays to get the metric position of the 3D points [ 4 , 5 ... If these measurements are stored, a temporal... more
Creating convincing representations of humans is a fundamental problem in both traditional arts and modern media. In our digital world, virtual avatars allow us to simulate and render the human body for a variety of applications,... more
This paper presents the first prototype of an interactive visualisation framework specifically designed for presenting geographical information in both indoor and outdoor environments. The input of our system is ESRI Shapefiles which... more
Potential applications of volume rendering in musculo-skeletal disorders Three dimensional imaging is increasingly important for evaluation of anatomic relationships and extent of disease, for treatment planning and for follow-up... more
