Abstract:
1. A method for segmenting images comprising: registering a first image having a first segmentable object; registering a second image having a second segmentable object, the second segmentable object having visual properties similar to the first segmentable object; extracting a plurality of first feature points from the first image; extracting a plurality of second feature points from the second image; matching at least a portion of the plurality of first feature points with at least a portion of the plurality of second feature points to identify a plurality of matched feature points for at least one of the first and second images; classifying the plurality of matched feature points as one of a foreground area and a background area; segmenting at least one of the first and second segmentable objects from at least a respective one of the first and second images based on the plurality of matched feature points in the foreground area; registering a third image having a third segmentable object with visual properties substantially similar to the first segmentable object; extracting a plurality of third feature points from the third image; matching at least a portion of the plurality of matched feature points with at least a portion of the plurality of third feature points so as to identify a plurality of commonly matched feature points between the first, second and third images; classifying the plurality of commonly matched feature points as one of a foreground area and a background area; and segmenting at least one of the first, second and third segmentable objects from at least a respective one of the first, second and third images based on the plurality of commonly matched feature points in the foreground area.
