Unblur
Unblur is used to align the frames of movies recorded on an electron microscope to reduce image blurrig due to beam-induced motion. It reads stacks of movies that are stored in MRC/CCP4 format. Unblur generates frame sums that can be used in subsequent image processing steps and optionally applies an exposure-dependent filter to maximize the signal at all resolutions in the frame averages. Movie frame sums can also be calculated using Summovie, which uses the alignment resuls from a prior run of Unblur.
