QuickPALM: 3D real-time photoactivation nanoscopy image processing in ImageJ Nature Methods 7, 339 - 340 (2010) doi:10.1038/nmeth0510-339
PALM and STORM reconstruction algorithms usually rely on 'fitting' Gaussian kernels to detected diffraction-limited spots. Although they permit high-accuracy localizations, these iterative methods can require up to several hours of processing time. We have developed a high-speed reconstruction algorithm that uses the classical Högbom 'CLEAN' method8 for spot finding, followed by a modified center of mass algorithm to compute the spot position and parameters defining spot shape along the horizontal axes.
I have not yet tried this, but seems to be very usable also for simple cases that needs to find spots. Plugin could be downloaded from
