}In this paper we introduce a novel representation of the significant changes in curvature along the bounding contour of planar shape. We call the representation the Curvature Primal Sketch because of the close analogy to the primal sketch representation advocated by Marr for describing significant intensity changes. We define a set of primitive parameterized curvature discontinuities, and derive expressions for their convolutions with the first and second derivatives of a Gaussian. We describe…

This paper describes a new symbolic representation for planar curves based on a segmentation of the curve based on regions of uniform curvature that decomposes the curve at multiple scales and the parts produced appear to correspond to a natural decomposition of the curves.

The proposed definition of visual curvature is the first ever that applies to regular curves as defined in differential geometry as well as to turn angles of polygonal curves and it yields stable curvature estimates of curves in digital images even under sever distortions.

Mathematics

The problem of finding a description, at varying levels of detail, for planar curves and matching two such descriptions is posed and solved and the result is the ``generalized scale space'' image of a planar curve which is invariant under rotation, uniform scaling and translation of the curve.

It is argued that "non-attentive" vision is in practice implemented by these grouping operations and first order discriminations acting on the primal sketch, and implies that such knowledge should influence the control of, rather than interfering with, the actual data-processing that is taking place lower down.
The Low-level Symbolic Representation of Intensity Changes in an Image

Biology
A family of symbols is defined by which much of the useful information in an image may be represented, and it is shown that these descriptors may readily be computed from measurements similar to those made by simple cells in the visual cortex of the cat.
