View-Graph Selection Framework for SfM
2018View-graph selection is a crucial step for accurate and efficient large-scale structure from motion (sfm). Most sfm methods remove undesirable images and pairs using several fixed heuristic criteria, and propose tailor-made solutions to achieve specific reconstruction objectives such as efficiency, accuracy, or disambiguation.

The sequential calculus SFM (acronym of Sequential Finite-state Machines) is equipped with an operational LTS semantics and an operational Petri net semantics; we observe that the two semantics are essentially isomorphic. We prove that all and only the sequential finite-state machines are the models of the Petri net semantics for SFM.

Force Measurements on a Hydrogel with an SFM
Journal of Colloid and Interface Science, 1995Abstract A scanning force microscope (SFM) has been to measure the force interactions between a pyramidal silicon nitride tip and a dextran hydrogel immersed in PBS solutions with various concentrations. The dextran gel was attached to a gold surface via alkane chains. Samples with only alkane chains attached to the gold surface served as a reference

Reduced epipolar cost for accelerated incremental SfM
CVPR 2011, 2011We propose a reduced algebraic cost based on pairwise epipolar constraints for the iterative refinement of a multiple view 3D reconstruction. The aim is to accelerate the intermediate steps required when incrementally building a reconstruction from scratch.

Scanning Force Microscopy (SFM)
1992The scanning tunneling microscope (STM) has revolutionized the field of microscopy. Even newer scanning microscopes are being developed which are based on piezoelectric transducers and sharp probing tips that scan a surface while a feedback loop regulates the distance between the probing tip and sample. In 1986 Binniget al.

Error Characteristics of SFM with Erroneous Focal Length
2006This paper presents a theoretical analysis of the behavior of “Structure from Motion” (SFM) algorithms with respect to the errors in intrinsic parameters of the camera. We demonstrate both analytically and in simulation how uncertainty in the calibration parameters gets propagated to motion estimates.
