A Critique of Structure-from-Motion Algorithms

, 2000
I critique current approaches to structure from motion and describe a new framework for algorithms. Keywords Structure from motion, multi--frame structure from motion, projective methods, invariants, self--calibration, Kalman filtering, optimization ...

Comparing motion induction in lateral motion and motion in depth [PDF]

, 2008
Induced motion, the apparent motion of an object when a nearby object moves, has been shown to occur in a variety of different conditions, including motion in depth.

Potential of Low-Cost UAV Photogrammetry for Documenting Hard-to-Access Interior Spaces Through Building Openings

Heritage
Unmanned aerial vehicles (UAVs) are primarily used in the field of cultural heritage for mapping the exteriors of larger objects and documenting the roofs and façades of tall structures that cannot be efficiently or feasibly measured using conventional ...

Combining Dense Structure From Motion and Visual SLAM in a Behavior-Based Robot Control Architecture

, 2010
In this paper, we present a control architecture for an intelligent outdoor mobile robot. This enables the robot to navigate in a complex, natural outdoor environment, relying on only a single on-board camera as sensory input.

Drone mapping links reindeer browsing during an herbivory pulse to divergent vegetation community responses

Environmental Research: Ecology
Large herbivores regulate ecosystem structure and functioning across Earth’s biomes, but vegetation community responses to herbivory depend on complex interactions involving the timing and intensity of herbivory pressure and other, often abiotic ...

The Fractional OU Process: Term Structure Theory and Application [PDF]

The paper revisits dynamic term structure models (DTSMs) and proposes a new way in dealing with the limitation of the classical affine models. In particular, this paper expands the flexibility of the DTSMs by applying a fractional Brownian motion as the ...
