WebFeb 17, 2024 · Reliable low-light enhancement algorithms can not only help civilian devices overcome the problem of poor image quality at night, but also significantly improve the performance of advanced computer vision tasks such as object detection, object recognition, and object tracking at night [ 10 ]. WebDec 22, 2024 · Fourier ptychography captures intensity images with varying source patterns (illumination angles) in order to computationally reconstruct large space-bandwidth-product images. Accurate knowledge of the illumination angles is necessary for good image quality; hence, calibration methods are crucial, despite often being impractical or slow. Here, we …
WebThe parameters (including position and intensity) of the light sources can be self-calibrated. To realize the auto-calibration, we first use the distant lighting model to estimate the initial surface albedo map, and then with the estimated albedo map and the normal vector field fixed, the parameters of the near lighting model are optimized. WebNov 1, 2024 · Abstract. Defocused speckle imaging (DSI) is an optical technique where a diffuse object surface is illuminated by a laser source, and the scattered interference speckle field is sampled by a defocused camera. The recorded image contains a speckle pattern. To solve the scaling problem, a diffraction-based self-calibration method is …
