In medical diagnostic imaging, the X-ray CT scanner and the MRI system have been widely used to examine 3D shapes and internal structures of living organisms and bones. However, these apparatuses are generally large and very expensive. Since an appointment is also required before examination, these systems are not suitable for urgent fracture diagnosis in emergency treatment. However, X-ray/flu...

The mechanical properties of sandwich composites are more depended on the core material structure. Damage commercial honeycomb materials generally occurred as delamination unit-cells under or impact loads. In addition, common feature is their high-cost. Economic approach current researches led studies based principle converting ordinary into advanced materials. Nowadays, development low-cost/hi...

We propose 3D-visualization in order to facilitate the assimilation of computerrepresented knowledge by human minds. Since human imagination and reasoning is based on 3D-shapes, the presentation and validation of knowledge is most efficiently performed with the aid of geometric shapes. We motivate the need for visualization in Knowledge Management applications supported by a case study modellin...

ABSTRACT The aims of this study were to (1) understand the concept geometry with geometric material, (2) (3) transformation and (4) development numeration contained in design. Saung Ranggon traditional house. This is a qualitative research conducted using an ethnographic approach explore through use materials materials, as well within design data collection techniques used included interviews, ...

The spatial pattern of reflected light carries detailed but ambiguous information about 3D shapes of illuminated objects. A little studied factor that affects the perceived 3D relief of 2D shaded figures is the shape of their contours. An experiment is reported in which 102 subjects matched twelve contoured grating displays (horizontal three-cycle gratings with variously shaped top and bottom c...

The recent development of retrieval techniques and advances in 3D shape representation has induced a large amount of research. This paper presents a methodology with three options to retrieve shapes in 3D data bases, based on mapping shapes in 1D using representative sequences, which are matched using Fast Dynamic Time Warping distance. The three options are compared through a performance measu...

We propose a new method for measuring three-dimensional (3D) moving facial shapes. This method uses photometric stereo method and slit pattern projection method with color light sources. The time required for sampling data can be reduced by switching the color light rays at high speed, and hence a series of 3D shapes of a moving human face at each instant can be measured. Experimental results a...

Today, immersive environments mainly use a few 3D positions given by trackers to align the real and virtual worlds. In this paper we present an alternative approach using commodity components to achieve real time marker-less 3D modeling in virtual reality environments. The goal is to compute in real time a 3D shape of the objects and users present in the interaction space without having to equi...

For 3D model-based approaches, building the 3D shape model from a training set of segmented instances of an object is a major challenge and currently remains an open problem. In this paper, we propose a novel, general method for the generation of 3D statistical shape models. Given a set of training 3D shapes, 3D model generation is achieved by 1) building the mean model from the distance transf...

3D reconstruction from a single image is a classical problem in computer vision. However, it still poses great challenges for single-view reconstruction of daily-use objects with irregular1 shapes. In this paper, we re-consider the problem of single-view 3D reconstruction in terms of two CV areas: category modeling and knowledge mining from big visual data. Category modeling & task output: For ...
