 | Two researchers from the University of Salamanca have developed a procedure to enable forensic police to extract metric data from crime scenes using just a single photograph. Their proposal, published recently in the Journal of Forensic Sciences, makes it possible to reconstruct a crime scene in 3-D. ...> Full Article |
 | Computer Scientist Hany Farid has new evidence regarding a photograph of accused JFK assassin Lee Harvey Oswald. Farid digitally analyzed the iconic image of Oswald pictured in a backyard setting holding a rifle in one hand and Marxist newspapers in the other, and he says the photo almost certainly was not altered. ...> Full Article |
Errant pixels and blurry regions in a photo, whether digital or scanned, are the bane of photographers everywhere. Moreover, in vision processing research degraded photos are common and require restoration to a high-quality undegraded state. Research published this month in the International Journal of Signal and Imaging Systems Engineering could provide new insights.
