摘      要:Improving the spatial resolution of a fluorescence microscope has been an ongoing challenge in the imaging *** address this challenge,a variety of approaches have been taken,ranging from instrumentation development to image *** example of the latter is deconvolution,where images are numerically deblurred based on a knowledge of the microscope point spread ***,deconvolution can easily lead to noise-amplification *** by postprocessing can also lead to negativities or fail to conserve local linearity between sample and *** describe here a simple image deblurring algorithm based on pixel reassignment that inherently avoids such artifacts and can be applied to general microscope modalities and fluorophore *** algorithm helps distinguish nearby fluorophores,even when these are separated by distances smaller than the conventional resolution limit,helping facilitate,for example,the application of single-molecule localization microscopy in dense *** demonstrate the versatility and performance of our algorithm under a variety of imaging conditions.
