WebApr 11, 2024 · 1.Introduction. Intense scattering occurs as the light propagates through biological tissues, smoke, ground glass, or other scattering media. In such cases, it is tough for the conventional optical camera to capture the image of the object due to the distortion of the light field [1].However, the information about the object is still in the distorted light … WebThe DOE structure partially resembles that of a grating, which creates multiple peaks in the point spread function (PSF, right). Intuitively, this PSF creates three shifted and scaled copies of the input image. ... Deep Optics for Depth Estimation and Object Detection. ICCV 2024 ; Peng et al. 2024.
