N Observation Photon Counting Imaging With Preprocessing

In this paper, we explain our method to enhance the conventional integral imaging method. The photon-counting imaging is used to obtain the image including objects or scene under photon-lacked environments. And the conventional
$N$
observation photon counting imaging obtains three-dimensional (3D) image by repeating the estimation to obtain more accurate information of object or scene than conventional photon-counting imaging under almost photon-lacked environments. To enhance the visual quality and information of 3D objects in the conventional
$\mathrm{N}$
observation photon counting imaging, the volumetric computational reconstruction (VCR) is utilized as preprocessing and combined
