Remember the Polaroid camera- that black box capable of spitting out an image within seconds of snapping the shutter? Once the star of social gatherings, a Polaroid camera now sits on a shelf in Bill Freeman’s office at CSAIL, a relic of a time gone by. The world of photography has transformed dramatically since Freeman worked for Polaroid in the field of electronic imaging during the 1980s. Digital cameras have since made photography an art form easily accessible to all, with images ready for viewing the moment they are captured, numerous computer programs available for editing and websites hosting platforms for millions to share their snapshots.
This progression shows the results of Durand and Freeman’s work with image deblurring. On the left there is a picture taken with a conventional camera of an object in motion, the center image was captured with a camera designed to capture a specific type of motion and remove blur, and the photo on the right shows the resulting image after deconvolution.
Frédo Durand, Bill Freeman, Taeg Sang Cho and Anant Levin published a paper on their work with "Motion blur with orthogonal parabolic exposures" in 2010.
