What began as an effort to better understand how animal and
human visual systems work has led to a revolutionary method for enlarging and
enhancing photos that is being made available, free of charge, from the Center
for Perceptual Systems at The University of Texas at Austin.
Wilson Geisler, center director and professor in the
Department of Psychology, said that the free image-processing website allows
users to upload as many as 1,000 images daily. The site provides tools to
“de-noise” images — such as removing imperfections resulting from low light
conditions — and allows users to enlarge images without losing picture quality.
