1979 A Simplified Derivation of Frei's Histogram Hyperbolization for Image Enhancement
abstract
Frei has recently introduced a new technique (histogram hyperbolization) for image enhancement by the manipulation of the picture brightness levels. An alternative derivation of Frei's result, both simpler and more general, is presented.

1972 A Parallel Mechanism for Describing Silhouettes
abstract
We describe a parallel mechanism, based on an array of circularly nutating photodetectors, that computes an approximation of the density of slopes of the boundary of any piecewise regular silhouette. This density, when properly normalized, is invariant with respect to the size, translation, and orientation of the given silhouette.
