Opis

Over the past centuries visual illusions have provided us with a betterunderstanding of the human visual system. This book contributes to thisresearch field by utilizing visual illusions as research tools in severalpsychophysical experiments and qualitative approaches. Since the humanvisual system is complex and processing mechanisms are highly interactive innetworks, the focus is not on a single field but rather an investigation of awhole series of visual illusions. The work is divided into three major threads:1. phenomena of fading and filling-in; 2. geometric-optical illusions,luminance illusions, and color illusions at conditions of luminance contrastand isoluminance with chromatic contrast; 3. apparent motion illusions.These studies expand our knowledge on various processing mechanisms fromlow-level to higher-levels of the visual cortex.. The results of the studies areinterpreted and discussed within the context of current research work in thefield of Vision Sciences. Furthermore, some new visual (illusory) phenomenaare introduced, which could serve as valuable tools for future research inpsychophysical, physiological, or brain imaging studies.
