1. A method, comprising, receiving input indicative of a user selection of a shared visual feature shared by a first digital image and a second digital image comprising a stereo image pair in connection with a display of the first digital image and the second digital image in a user interface, the input indicative of a region of the stereo image pair corresponding to the shared visual feature; and calculating, based on the received input, a boundary of the region corresponding to the user selection that contains the shared visual feature in the first digital image and the second digital image, by constructing probabilities that sets of pixels in the first digital image and the second digital image are within the boundary and correspond to one another; and selecting the shared visual feature contained within the calculated boundary in both the first digital image and the second digital image of the stereo image pair for subsequent image editing operations.
