SUMMARY:Plug-and-Play Algorithms for Dynamic Non-line-of-sight Imaging
DESCRIPTION:Technical Papers\n\nXin Yuan (Westlake University), JunTian Ye
  and Yu Hong (University of Science and Technology of China), Xiongfei Su 
 (Westlake University), and Feihu Xu (University of Science and Technology 
 of China)\n\nNon-line-of-sight (NLOS) imaging has the ability to recover 3
 D images of scenes outside the direct line of sight, which is of growing i
 nterest for diverse applications. Despite the remarkable progress, NLOS im
 aging of dynamic objects is still challenging. It requires a large amount 
 of multibounce photons for the reconstruction of single frame data. To ove
 rcome this obstacle, we develop a computational framework for dynamic time
 -of-flight NLOS imaging based on plug-and-play (PnP) algorithms. By combin
 ing imaging forward model with the deep denoising network from the compute
 r vision community, we show a 4 frames-per-second (fps) 3D NLOS video reco
 very (128 × 128 × 512) in post processing. Our method leverages the tempor
 al similarity among adjacent frames and incorporates sparse priors and fre
 quency filtering. This enables higher-quality reconstructions for complex 
 scenes. Extensive experiments are conducted to verify the superior perform
 ance of our proposed algorithm both through simulations and real data.\n\n
