The structure of images
JJ Koenderink - Biological cybernetics, 1984 - Springer
In practice the relevant details of images exist only over a restricted range of scale. Hence it
is important to study the dependence of image structure on the level of resolution. It seems …

The internal representation of solid shape with respect to vision
JJ Koenderink, AJ Van Doorn - Biological cybernetics, 1979 - Springer
It is argued that the internal model of any object must take the form of a function, such that
for any intended action the resulting reafference is predictable. This function can be derived …

Optic flow
JJ Koenderink - Vision research, 1986 - Elsevier
This paper offers a quick review of the subject of “optic flow” in its conceptual and
computational aspects. The theory is evaluated in terms of possible applications in the …

Surface shape and curvature scales
JJ Koenderink, AJ Van Doorn - Image and vision computing, 1992 - Elsevier
The classical surface curvature measures, such as the Gaussian and the mean curvature at
a point of a surface, are not very indicative of local shape. The two principal curvatures (…

Affine structure from motion
JJ Koenderink, AJ Van Doorn - JOSA A, 1991 - opg.optica.org
A mobile observer samples sequences of narrow-field projections of configurations in
ambient space. The so-called structure-from-motion problem is to infer the structure of these …

What does the occluding contour tell us about solid shape?
JJ Koenderink - Perception, 1984 - journals.sagepub.com
A new theorem is discussed that relates the apparent curvature of the occluding contour of a
visual shape to the intrinsic curvature of the surface and the radial curvature. This theorem …

Representation of local geometry in the visual system
JJ Koenderink, AJ van Doorn - Biological cybernetics, 1987 - Springer
It is shown that a convolution with certain reasonable receptive field (RF) profiles yields the
exact partial derivatives of the retinal illuminance blurred to a specified degree. Arbitrary …

The singularities of the visual mapping
JJ Koenderink, AJ Van Doorn - Biological cybernetics, 1976 - Springer
In this article we treat purely metrical properties of the visual image, eg the time changes of
the relative positions and orientations of image details. Self-induced movements of an …

Surface perception in pictures
Subjects adjusted a local gauge figure such as to perceptually “fit” the apparent surfaces of
objects depicted in photographs. We obtained a few hundred data points per session, …

Generic neighborhood operators
JJ Koenderink, AJ van Doorn - IEEE Transactions on Pattern Analysis …, 1992 - computer.org
A method that treats linear neighborhood operators within a unified framework that enables
linear combinations, concatenations, resolution changes, or rotations of operators to be …
