the aim of this study was to reveal biometric peculiarities of new zealand white rabbit antebrachium (radius and ulna) by means of three-dimensional (3d) reconstruction of multidetector computed tomography (mdct) images. under general anesthesia, the antebrachiums of a total of sixteen rabbits of both sexes were scanned with a general diagnostic mdct. biometric measurements of the reconstructed...

In this paper, we describe a system for video-based 3D reconstruction of dynamic scenes using stereo techniques, with an eye to potential applications in human motion capture. We incorporate into our approach recent research results on stereo matching which make the system efficient and produce good-quality results. The implementation is built on top of Intel’s Open Source Computer Vision Libra...

The main contribution of this paper is to present a novel method for automatic 3D face recognition based on sampling a 3D mesh structure in the presence of noise. A structured light method using line projection is employed where a 3D face is reconstructed from a single 2D shot. The process from image acquisition to recognition is described with focus on its real-time operation. Recognition resu...

Three-dimensional tools are widely used for various purposes, particularly Three- dimensional printers which play a great role in simplification and acceleration of phases in production process for various fields ranging from medicine to industry. Due to the problems related to the reconstruction of missing parts in restoration of historic glass objects in the methods of molding, casting and f...

The selection of effective and optimal sidelap/overlap of images according to the quality, speed, cost and purpose of each UAV photogrammetric project is considered as an important parameter. Since two decades ago, several researches have been carried out based on a trial and error strategy for this purpose, in which different drones and cameras have been utilized for imaging with different sid...

conclusion osem3d may provide better image quality and higher contrast than other methods for small animal imaging with the new myocardial imaging agent, [18f] fptp. results the location and size of myocardial infarction on pet images correlated closely with that observed with ttc staining. among the four reconstruction methods, osem3d provided the best assessment of infarct size (r2 = 0.994, p...
