"University of Texas at Austin researchers have discovered how to
extract and use information in an individual image to determine how far
objects are from the focus distance, a feat only accomplished by human
and animal visual systems until now," according to a
MedicalNewsToday post. "Johannes Burge, a postdoctoral fellow in the College of Liberal Arts'
Center for Perceptual Systems and co-author of the study, says it is
significant that a statistical algorithm can now determine focus error,
which indicates how much a lens needs to be refocused to make the image
sharp, from a single image without trial and error."
