3D Structure from Motion Using Homocentric Spherical Spatiotemporal Image Analysis
A technique for building a three-dimensional description of a static scene from a spatiotemporal image is presented. This technique utilizes Homocentric Spherical Spatiotemporal Image (HSSI) analysis and makes allowances for camera rotation, which is a wider class of camera motion than that in ordinary spatiotemporal image analysis. Experiments with real images from a translating and rotating c...
متن کاملLong Image Sequence Motion Analysis Using Polynomial Motion Models
The cameracentered motion representation is ([1][5][6]): This paper presents two algorithms for estimating motion and structure from long monocular image sequences: one using interframe correspondences, the other using point trajectories. Object-centered motion represenfations and motion models &scribed by up to the second order polynomials are used to estimate motion parameters from long image...
متن کاملExact Two-Image Structure from Motion
For two–image structure from motion, we present a simple, exact expression for a least–squares image– reprojection error for finite motion that depends only on the motion. Optimal estimates of the structure and motion can be computed by minimizing this expression just over the motion parameters. Also, we present a solution to the triangulation problem: an exact, explicit expression for the opti...
متن کاملFrom Electron Density and Sequence to Structure: Integrating Protein Image Analysis and Threading for Structure Determination
This paper presents a computational methodology for integrating techniques from protein image interpretation and protein sequence threading, applied to the problem of structure determination from experimental X-ray crystallographic electron density maps. In the proposed architecture, image interpretation of an electron density map produces candidate structural segments; threading is applied to ...
متن کاملStructure and motion from image sequences
In this paper an approach is presented that obtains virtual models from sequences of images. The system can deal with uncalibrated image sequences acquired with a hand held camera. Based on tracked or matched features the relations between multiple views are computed. From this both the structure of the scene and the motion of the camera are retrieved. The ambiguity on the reconstruction is res...
