Computational Imaging with Light Waves
Seung-Hwan Baek

Modern imaging systems have evolved to effectively capture light. Through continuous developments, our ability to capture the real world now rivals that of the human visual system. However, capturing light in full fidelity is still challenging and one fundamental reason originates from the fact that light has the duality as particles and waves. Most imaging devices are not optimized to capture light as waves, therefore, losing valuable information of the real world hidden in those wave properties. This talk includes several studies of capturing, analyzing, and exploiting overlooked dimensions of light waves, namely spectrum and polarization, in order to solve problems in computer graphics and vision. We develop computational imaging systems with the core principle of jointly designing optics and algorithms to decode the delicate interaction of light waves and materials. We demonstrate three specific applications: RGB-D imaging from polarimetric double refraction, spectrum from dispersion, and appearance from polarization.
