3D Reconstruction from Single 2D Image
The perception of 3D scene with stereovision is the capability of human vision but it is a challenge to computer systems. The challenge is to obtain 3D geometric shape information from planar images. This is termed as 3D reconstruction. It is usually done in a piece-wise fashion by identifying various planes of the scene and from those planes constructing a representation of the whole. The imag...
متن کامل3D Reconstruction from a Single Image
A probabilistic framework for 3D object reconstruction from a single image is introduced in this work. First, a probabilistic generative model to represent the distribution of mass of a class of objects in 3D space, namely a 3D shape prior, is presented. Next, following the Beer-Lambert law in optics, a framework to translate these 3D probabilities into the corresponding 2D probabilities in the...
متن کامل3d Object Reconstruction from a Single Image
This paper describes the photogrammetric techniques and approaches developed for 3D object reconstruction based on a single image. It is possible to get metric information from a single view when the stereo-based photogrammetric technique is not available. In this scope some advanced multidisciplinary techniques which allow an automatic capture of meaningful elements for perspective models from...
متن کاملFull 3d Roi Image Reconstruction from Highly Collimated Computed Tomography
We introduce a novel method for full 3D Region Of Interest (ROI) reconstruction in computed tomography (CT), called Searchlight CT, which reduces the overall radiation exposure when primarily the reconstruction of a specified ROI is required. To achieve this goal, the Searchlight CT approach restricts the acquisition essentially to X-rays passing through the ROI, yet the algorithm provides a st...
متن کامل3D Reconstruction of Reflection Nebulae from a Single Image
This paper presents a method for reconstructing the 3D distribution of dust densities in reflection nebulae based on a single input image using an analysisby-synthesis approach. In a reflection nebula, light is typically emitted from a central star and then scattered and partially absorbed by the nebula’s dust particles. We model the light transport in this kind of nebulae by considering absorp...
