Three‐Dimensional Reconstruction of Tissues

Current Protocols in Molecular Biology, 2006
AbstractCellular morphology is inherently three‐dimensional. However, most histological techniques for tissue analysis focus on extracting information from two‐dimensional slices of fixed samples or dissociated cells. These techniques result in a significant loss of the three‐dimensional information of the tissue, including true cell volume ...

Three-dimensional reconstruction by zooming

IEEE Transactions on Robotics and Automation, 1993
It is shown that it is possible to infer 3-D information from a set of images taken with a zoom lens. A precise study of the optical properties of such a lens gives two major results: The intersection between the optical axis and the image plane can be independently and accurately determined, and the pin-hole model cannot be used directly for the ...

Otocephalus: Histopathology and three-dimensional reconstruction

Otolaryngology - Head and Neck Surgery, 1996
Otocephaly is a lethal malformation of the first and second branchial arches, which consists of ventromedial displacement of the external ear structures (synotia), mandibular aplasia (agnathia), absence of the tongue (aglossia), and microstomia. We present the first complete description of the temporal bone findings in a case of otocephalus.

A review of three dimensional reconstruction techniques

Multimedia Tools and Applications, 2021
Three dimensional (3D) modeling is an important stereoscopic representation of an object for multiple viewpoints aggregation and geometrical information. A general 3D modeling pipeline consists of data acquisition, 3D reconstruction and surface reconstruction. The core computational process in 3D modeling is always associated with the 3D reconstruction,

Three-Dimensional Reconstruction of Human Interactions

2020 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR), 2020
Understanding 3d human interactions is fundamental for fine grained scene analysis and behavioural modeling. However, most of the existing models focus on analyzing a single person in isolation, and those who process several people focus largely on resolving multi-person data association, rather than inferring interactions.

Three-dimensional reconstruction of the rat acinus

Journal of Applied Physiology, 1987
This study provides a quantitative description of the small airways and alveolar duct-alveolar architecture of the rat lung. To accomplish this, quantitative three-dimensional reconstructions were made of small airways, the alveolar duct system, and alveoli.
