Fast and robust misalignment correction of Fourier ptychographic microscopy

no code implementations20 Feb 2018 Ao Zhou, Wei Wang, Ni Chen, Edmund Y. Lam, Byoungho Lee, Guohai Situ

Fourier ptychographi cmicroscopy(FPM) is a newly developed computational imaging technique that can provide gigapixel images with both high resolution (HR) and wide field of view (FOV).

Analysis of the noise in back-projection light field acquisition and its optimization

no code implementations30 Dec 2016 Ni Chen, Zhenbo Ren, Dayan Li, Edmund Y. Lam, Guohai Situ

In this paper, we analyze the defocus noise and the depth resolution in the focal plane sweeping based light field reconstruction technique, and propose a method to reduce the defocus noise and improve the depth resolution.
