Generative adversarial network based single pixel imaging
Ming Zhao, Fengqiang Li, Fengyue Huo +1
Single pixel imaging can reconstruct two-dimensional images of a scene with only a single-pixel detector. It has been widely used for imaging in non-visible bandwidth (e.g., near-i…
Adaptive Illumination based Depth Sensing using Deep Superpixel and Soft Sampling Approximation
Qiqin Dai, Fengqiang Li, Oliver Cossairt +1
Dense depth map capture is challenging in existing active sparse illumination based depth acquisition techniques, such as LiDAR. Various techniques have been proposed to estimate a…
Exploiting wavelength diversity for high resolution time-of-flight 3D imaging
Fengqiang Li, Florian Willomitzer, Prasanna Rangarajan +1
State-of-the-art time-of-flight (ToF) based 3D sensors suffer from poor lateral and depth resolutions. In this work, we introduce a novel sensor concept that provides ToF-based 3D…
Synthetic Wavelength Holography: An Extension of Gabor's Holographic Principle to Imaging with Scattered Wavefronts
Florian Willomitzer, Prasanna V. Rangarajan, Fengqiang Li +3
The presence of a scattering medium in the imaging path between an object and an observer is known to severely limit the visual acuity of the imaging system. We present an approach…
Photometric Stereo by UV-Induced Fluorescence to Detect Protrusions on Georgia O'Keeffe's Paintings
Johanna Salvant, Marc Walton, Dale Kronkright +4
A significant number of oil paintings produced by Georgia O'Keeffe (1887-1986) show surface protrusions of varying width, up to several hundreds of microns. These protrusions are s…
