Perceptual-based Rendering in Computer Graphics

Visual perception refers to a mode that human visual system (HSV) interprets optical information from visible light reaching the eye. Optical illusion, a phenomenon that HSV misinterprets the received information from its physical reality, is always fascinating to look at and has been extensively investigated across multiple disciplines including cognitive psychology, neurobiology, computer vision and graphics. In their art forms, optical illusions are delicately manipulated via artists to create illusory images. Inspired by these artpieces, researchers in computer graphics community have dedicated to combine perceptual theories with modern computer graphics techniques to create illusory images. These works not only open a novel research category, named recreational graphics, but also benefit cognitive psychology and neurobiology in supporting large set of experimental data. In this speech, I will give an introduction of optical illusion and recent advances of illusory rendering in computer graphics. Two of my research projects about emergence and camouflage rendering will be presented and discussed.
