Abstract:

Computational photography is an emerging field with continuing advances in both theory and applications. Computational photography has led to diverse imaging applications, including two-dimensional images, videos, hyperspectral images, depth, x-ray, millimeter wave, polarization, microscopy and Terahertz imaging. In this talk, we will start from the lensless camera, and based on the space-time-spectrum tradeoff, introduce the underlying principle of spatial/video/spectral computational imaging. The imaging architectures of various computational cameras will be described. As a pivot role in computational imaging, reconstruction will be introduced too. Aiming to bridge the gap in virtual reality, compressive high-speed 3D imaging systems will be discussed.
