New Vision Tools from the Comparative Study of an "Old" Psychophysical and a "Modern" Computational Model

A comparative study has been made between a one and half century old psychophysical model of vision and a modern computational model. The Mach band illusion has been studied from a new angle, that led to concluding that a Bi-Laplacian of Gaussian operation is a likely possibility in the visual system along with the traditional Laplacian operation. As a follow-up to this, exploring the human visual system through a two-pronged approach, based on the two models mentioned above, has helped in the construction of a new image sharpening kernel, on one hand and possibilities of new algorithms for robust visual capturing and image halftoning and compression on the other.
