Input and output of the semiautomated blurring algorithm. The algorithm can estimate the blur pattern required to simulate a desired focal length. It can either derive scene information from parallel lines in a scene or use manual feedback from the user on the overall orientation of the scene. (a) Two pairs of parallel lines were selected from a carpentered scene for use with the first approach. (b) The resulting image once blur was applied. Intended focal distance = 0.06m. (c) A grid was manually aligned to lie parallel to the overall scene. (d) The blurred output designed to simulate a focal distance of 0.50m.
