WebJan 3, 2014 · We introduce a low-flux imaging technique, called first-photon imaging, which is a computational imager that exploits spatial correlations found in real-world scenes and the physics of low-flux measurements. Our technique recovers 3D structure and reflectivity from the first detected photon at each pixel. WebMar 18, 2024 · The fundamental of first-photon imaging is to exploit the spatial correlations among detection area pixels and use Sparse Poisson Intensity Reconstruction …

Researching First-photon imaging via a hybrid penalty

Weband efficiently. Here, a new hybrid penalty is proposed for the convex optimization algorithm of first-photon imaging, and its principle is given as follows. A. Pixelwise Reflectivity … WebFirst-photon imaging is a photon-efficient, computational imaging technique that reconstructs an image by recording only the first-photon arrival event at each spatial location and then...
