  • Patent number: 7778487
    Abstract: A technique for image compositing which allows a user to select the best image of an object, such as for example a person, from a set of images interactively and see how it will be assembled into a final photomontage. A user can select a source image from the set of images as an initial composite image. A region, representing a set of pixels to be replaced, is chosen by the user in the composite image. A corresponding same region is reflected in one or more source images, one of which will be selected by the user for painting into the composite image. The technique optimizes the selection of pixels around the user-chosen region or regions for cut points that will be least likely to show seams where the source images are merged in the composite image.

  • Patent number: 7519907
    Abstract: A system and method for editing images. A simple but powerful image stack is employed in creating an enhanced image from a stack of registered images. This paradigm combines pixels using multi-image operations on the image stack. Image Stacks can help create group photographs, create high dynamic range images, combine images captured under different lighting conditions, remove unwanted objects from images, and combine images captured at different times and with different focal lengths.
