Abstract

The present application proposes a light field deconvolution method and device in the Fourier domain, which relate to the technical field of computer photography, wherein the method includes: acquiring light field microscopic data, and combining the light field microscopic data through random angles Two-by-two combination is performed to form multiple groups of angle subgroups; multiple groups of angle subgroups are input into the Fourier domain for reconstruction iterative processing to obtain a reconstructed image. Compared with the prior art, the present application combines the obtained light field microscopic data in pairs by means of random angle combination to form multiple sets of angle subgroups, and the formed multiple sets of angle subgroups in the Fourier domain The solution for 3D reconstruction realizes artifact-free reconstruction, reduces computing cost, and speeds up the reconstruction speed of 3D imaging.

Description

technical field [0001] The present application relates to the technical field of computer photography, in particular to a method and device for deconvolution of a light field in the Fourier domain. Background technique [0002] A large number of biokinetic experiments can only be captured at high speed in 3D, which poses a great challenge to current microscopy techniques. Light field microscopy (LFM) is an elegant computational solution with a compact system. By capturing the spatial and angular information in snapshots, LFM can recover high-speed 3D information through different algorithms, and then explore various fields through the recovered high-speed 3D information. biological applications, especially for large-scale 3D observation of neural activity. However, the reconstructed images obtained by existing techniques suffer from severe artifacts, high computational cost and slow restoration speed. Contents of the invention [0003] This application aims to solve one ...
