Photogrammetry for 3D Reconstruction of Objects: Effects of Geometry, Texture and Photographing
Today, the use of 3D scanning methods is increasing in a wide range of industries from biomedical to game production. The photogrammetry method is in demand by 3D scanning users due to its portability, photorealistic textured modeling, and low cost ...

Gaussian mixture model based probabilistic modeling of images for medical image segmentation [PDF]
In this paper, we propose a novel image segmentation algorithm that is based on the probability distributions of the object and background. It uses the variational level sets formulation with a novel region based term in addition to the edge-based term ...

Image-based façade modeling [PDF]
We propose in this paper a semi-automatic image-based approach to façade modeling that uses images captured along streets and relies on structure from motion to recover camera positions and point clouds automatically as the initial stage for modeling. We start by considering a building façade as a flat rectangular plane or a developable surface with an

Fatigue crack in cast aluminum alloys subject to low-cycle fatigue is initiated mainly by the fracture of Si particles. To investigate the mechanism of Si particle fracture, we carried out the geometrical measurements and finite element analysis for a ...

Thanks to the advances in integrating photogrammetry and computer vision, as well as in some numeric algorithms and methods, it is possible to aspire to turn 2D (images) into 3D (point clouds) in an automatic, flexible and good-quality way.

Large Margin Image Set Representation and Classification [PDF]
In this paper, we propose a novel image set representation and classification method by maximizing the margin of image sets. The margin of an image set is defined as the difference of the distance to its nearest image set from different classes and the ...

Understanding Vasomotion of Lung Microcirculation by In Vivo Imaging
The balance of lung extravascular water depends upon the control of blood flow in the alveolar distribution vessels that feed downstream two districts placed in parallel, the corner vessels and the alveolar septal network. The occurrence of an edemagenic

Hardware architecture for lossless image compression based on context-based modeling and arithmetic coding [PDF]
In this paper we present a novel hardware architecture for context-based statistical lossless image compression, as part of a dynamically reconfigurable architecture for universal lossless compression.

Image-based street-side city modeling [PDF]
We propose an automatic approach to generate street-side 3D photo-realistic models from images captured along the streets at ground level. We first develop a multi-view semantic segmentation method that recognizes and segments each image at pixel level into semantically meaningful areas, each labeled with a specific object class, such as building, sky,
