Abstract:
A method for identifying a border in a digital image, the digital image defined by a plurality of pixels, each pixel defined by a pixel color and a pixel position indicating a location of the pixel in the digital image, the method comprising:receiving as an input an area of interest that includes at least a portion of the border to be identified; estimating information about an edge zone that models the border portion, the estimating including: estimating a position of the edge zone including calculating a weighted average value of pixel positions of each pixel in the area of interest; estimating a width of the edge zone; calculating a measure of confidence in the edge zone information; and estimating a width of the edge zone at which the calculated measure of confidence decreases appreciably if the estimated edge zone width increases; and using the estimated edge zone information to identify the border.
