Patent number: 7702131Abstract: A sequence of images depicts a foreground object in motion. A base image is selected, and the other images in the sequence are co-registered with the base image in order to align the images to a common coordinate system. A background image and a binary foreground mask are generated from the sequence of aligned images. By applying the foreground mask to a chosen one of the aligned images, a representation of the moving object is extracted. After blurring the background image, the extracted representation may be superimposed onto the blurred background image to produce a new image.Type: GrantFiled: October 13, 2005Date of Patent: April 20, 2010Assignee: Fujifilm CorporationInventors: Troy Chinen, Sergey Ioffe, Thomas Leung, Yang Song
