SfM With MRFs: Discrete-Continuous Optimization for Large-Scale Structure From Motion [PDF]

open access: yesIEEE Transactions on Pattern Analysis and Machine Intelligence, 2013
Recent work in structure from motion (SfM) has built 3D models from large collections of images downloaded from the Internet. Many approaches to this problem use incremental algorithms that solve progressively larger bundle adjustment problems. These incremental techniques scale poorly as the image collection grows, and can suffer from drift or local ...

Dense-SfM: Structure From Motion With Dense Consistent Matching

open access: yes2025 IEEE/CVF Conference on Computer Vision and Pattern Recognition (CVPR)
We present Dense-SfM, a novel Structure from Motion (SfM) framework designed for dense and accurate 3D reconstruction from multi-view images. Sparse keypoint matching, which traditional SfM methods often rely on, limits both accuracy and point density, especially in texture-less areas.

Estimation of Hydromorphological Attributes of a Small Forested Catchment by Applying the Structure From Motion (SfM) Approach

open access: yesInternational Journal of Applied Earth Observation and Geoinformation, 2018
Abstract Structure from Motion (SfM) represents a good low-cost alternative to generate high resolution topography where LiDAR (Light Detection and Ranging) data is scarce or unaffordable. In this work, we demonstrate the advantages of high resolution elevation models (DEM) obtained using the SfM technique to delineate catchment boundaries and the ...
