A critique of structure-from-motion algorithms
J Oliensis - Computer Vision and Image Understanding, 2000 - Elsevier
I review current approaches to structure from motion (SFM) and suggest a framework for
designing new algorithms. The discussion focuses on reconstruction rather than on …

On event-based optical flow detection
Event-based sensing, ie, the asynchronous detection of luminance changes, promises low-
energy, high dynamic range, and sparse sensing. This stands in contrast to whole image …

An introduction to the log-polar map** [image sampling]
One interesting feature of the human visual system is the topological transformation of the
retinal image into its cortical projection. The excitation of the cortex can be approximated by …

Understanding noise sensitivity in structure from motion
Solutions to the structure from motion problem have been shown to be very sensitive to
measurement noise and the respective motion and geometry configuration. Statistical error …

Fixation simplifies 3D motion estimation
Fixation is defined as holding the gaze direction towards the same environmental point
through time. It was proven in the past that fixation reduces the number of unknowns in …

Direct perception of three-dimensional motion from patterns of visual motion
Measurements of retinal motion along a set of predetermined orientations on the retina of a
moving system give rise to global patterns. Because the form and location of these patterns …

Observability of 3D motion
This paper examines the inherent difficulties in observing 3D rigid motion from image
sequences. It does so without considering a particular estimator. Instead, it presents a …
