Image quality assessment based on a degradation model by Damera-Venkata, N., Kite, T.D., Geisler, W.S., Evans, B.L., Bovik, A.C.

“…We model a degraded image as an original image that has been subject to linear frequency distortion and additive noise injection. Since the psychovisual…”

Linear color-separable human visual system models for vector error diffusion halftoning by Monga, V., Geisler, W.S., Evans, B.L.

“…Image halftoning converts a high-resolution image to a low-resolution image, e.g., a 24-bit color image to a three-bit color image, for printing and display…”

Optimal eye movement strategies in visual search by Najemnik, J., Geisler, W.S.

“…To perform visual search, humans, like many mammals, encode a large field of view with retinas having variable spatial resolution, and then use high-speed eye…”
