    摘要: A technique for producing a foreground mask from a digital image is based on receiving two digital images, wherein a first digital image is derived from a first original scene image including a foreground photographed against a background having arbitrary and unknown content matter, and a second digital image is derived from a second original scene image including substantially the same background but without the foreground. The second digital image is automatically aligned to the first digital image without user intervention to generate an aligned digital image including the background without the foreground. Then, using the first digital image and the aligned digital image, a foreground mask is produced relating to the spatial regions in the first digital image pertaining to the foreground, whereby the foreground mask is subsequently used to generate a composite digital image.

    摘要: An electronic imaging system useful for compositing images includes an electronic camera for capturing multiple images, including a first image of a subject plus background and a second image of the background only. The first and second images are subtracted to generate a difference image, and the difference image is processed to generate a mask image. The mask image is then applied to the first image to select an area in which the subject is located, whereby the selected subject area is used in the compositing of a new image.

    摘要: A method for associating event times or time periods with digital images in a collection for determining if a digital image is of interest, includes storing a collection of digital images each having an associated capture time; comparing the associated capture time in the collection with a special event time to determine if a digital image in the collection is of interest, wherein the comparing step includes calculation of a special event time associated with a special event based on the calendar time associated with the special event and using such information to perform the comparison step; and associating digital images of interest with the special event.
