As single-photon imaging becomes progressively more commonplace in sensing applications such as low-light-level imaging, three-dimensional profiling, and fluorescence imaging, there exist a number of fields where multispectral information can also be

We demonstrate 3D time-of-flight imaging from a scattering target illuminated with a heralded single photon source. Our image reconstruction algorithm achieves millimeter depth resolution with only 0.3 average detected photons per image pixel.

Publikováno v: IEEE transactions on image processing : a publication of the IEEE Signal Processing Society.

This paper presents a new algorithm for the learning of spatial correlation and non-local restoration of single-photon 3-Dimensional Lidar images acquired in the photon starved regime (fewer or less than one photon per pixel) or with a reduced number

International audience; Light detection and ranging (Lidar) data can be used to capture the depth and intensity profile of a 3D scene. This modality relies on constructing, for each pixel, a histogram of time delays between emitted light pulses and d
