Toboggan contrast enhancement
John R. C. Fairfield · Proceedings of SPIE, the International Society for Optical Engineering/Proceedings of SPIE · 1992
Toboggan contrast enhancement is a noniterative, no-parameter, linear execution time method for selectively augmenting the contrast of multispectral images of arbitrary dimensionality. It can be adapted to enhance images given any image function embodying one's notion of what constitutes an edge, provided the function monotonically decreases with distance from edges.
