Degeneracies in Rolling Shutter SfM

2016
We address the problem of Structure from Motion (SfM) with rolling shutter cameras. We first show that many common camera configurations, e.g. cameras with parallel readout directions, become critical and allow for a large class of ambiguities in multi-view reconstruction.

An Iterative Multiresolution Scheme for SFM

2006
Several factorization techniques have been proposed for tackling the Structure from Motion problem. Most of them provide a good solution, while the amount of missing and noisy data is within an acceptable ratio. Focussing on this problem, we propose to use an incremenal multiresolution scheme, with classical factorization techniques.

The Basic Calculus: SFM

2017
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.

SFM-2026-013

This paper establishes statistical feature extraction and automatic classification methods for high-frequency acoustic emission pulse clusters in liquid rocket engine combustion chambers. An 8-dimensional feature vector is defined, and an automatic classification workflow based on wavelet-transform time-frequency feature extraction and unsupervised ...

SFM-2026-011

This paper systematically analyzes the regulatory mechanisms of cooling channel geometry on modal locking effects in liquid rocket engine combustion chambers. Quantitative relationships between channel geometric parameters—channel aspect ratio, wall rib thickness, and channel layout angle—and modal antinode displacement magnitudes are derived.

SFM-2026-016

Internal reference: SFM-2026-016. Version 1.1.0 (May 2026). This paper opens the solid-state battery sub-matrix of the Starfire Matrix project. It extends the gradient-driven vacancy-interfacial synergistic degradation framework from propulsion and thermal protection systems to electrochemical energy storage systems.

SFM-2026-002

This paper proposes Directed Cognitive Convergence (DCC), a methodological framework for systematically identifying and integrating knowledge fragments from disparate domains to accelerate complex engineering problem-solving. DCC addresses "unknown unknowns"—knowledge fragments whose very existence has not yet been recognized—through four operational ...

SFM-2026-032

This paper proposes a fundamental paradigm reconstruction: the ontological definition of the chip should shift from "computational tool" to "information field cultivator." Under the IFD framework, Moore's Law is reinterpreted as the continuous enhancement of information field order; Huawei's τ scaling is revealed as pushing chips from the diffusive to ...
