Recent advances in adaptive optics (AO) have led to the implementation of wide field-of-view AO systems. A number of wide-field AO systems are also planned for the forthcoming Extremely Large Telescopes. Such systems have multiple wavefront sensors o

A New Framework for Particle Detection in Low-SNR Fluorescence Live-Cell Images and Its Application for Improved Particle Tracking

Autor: Zhen Qiu, Weiping Lu, Lei Yang, Alan H. Greenaway

Publikováno v: IEEE Transactions on Biomedical Engineering. 59:2040-2050

Image denoising and signal enhancement are two common steps to improve particle contrast for detection in low-signal-to-noise ratio (SNR) fluorescence live-cell images. However, denoising may oversmooth features of interest, particularly weak feature

An adaptive non-local means filter for denoising live-cell images and improving particle detection

Autor: Lei Yang, Graeme Ball, Zhen Qiu, Ilan Davis, Alan H. Greenaway, Weiping Lu, Richard M. Parton

Publikováno v: Journal of Structural Biology

Fluorescence imaging of dynamical processes in live cells often results in a low signal-to-noise ratio. We present a novel feature-preserving non-local means approach to denoise such images to improve feature recovery and particle detection. The comm

We introduce an approach based on using an iterative simulated annealing algorithm to drive the outcome of femtosecond laser ablation towards a specific target shape by using a two-dimensional deformable mirror. Unlike previous work combining adaptiv
