Segmenting images and simulating motion blur using an image sequence
First Claim
Patent Images
1. A method for extracting a moving object representation from a series of images comprising:
- causing one or more processors to perform the steps of;
aligning each of the images in the series to a common coordinate system;
obtaining a background image from the aligned images;
extracting the moving object representation from a particular image of the aligned images based on the background image; and
detecting tiepoints among the images in the series,wherein the images in the series are aligned so that the detected tiepoints coincide in the common coordinate system.

Abstract
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.

13. A computer program product including a computer program code physically embodied on a computer readable medium, the computer program code, when executed, causing one or more computers to:
-
receive a series of images; align each of the images in the series to a common coordinate system; obtain a background image from the aligned images; extract a moving object representation from a particular image of the aligned images based on the background image; and detect tiepoints among the images in the series, wherein the images in the series are aligned so that the detected tiepoints coincide in the common coordinate system. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20)
