He is survived by his wife, Dagmar Dolan, and his 15 year old daughter Bronja Prazdny. Slava was recognized internationally as an expert in many aspects of human and machine perception. During his prolific career, he had published over 60 journal articles reporting research in human perception, stereo vision, image processing, robotics, perceptual reasoning and learning, adaptive neural networks, and psychophysics. Slava derived his greatest pleasure from concocting clever demonstrations aimed at destroying currently popular theories of perception His work on transparent random-dot stereograms, for example, challenges widely-held theories of stereopsis that rely on surface continuity assumptions to resolve depth ambiguities. We were fortunate to have worked beside Slava during his tenure in California.
