Abstract:
A method for segmenting an image formed of a plurality of pixels, comprising the steps of:detecting edges of the image, the edge-detected image including real edges and noise; scanning rows of the image to discriminate between the real edges and the noise, eliminating the noise of the image; projecting the image; and segmenting the image, wherein the scanning step includes the steps of: discriminating between real spaces and discontinuous edges; connecting the discontinuous edges between two adjacent edges; generating a first value by counting pixels corresponding to the real edges and the noise; generating a second value by counting pixels corresponding to the real spaces and the discontinuous edges; and comparing the first value and the second value with predetermined first threshold and second threshold, respectively, to verify the counted pixels according to the results of the comparison.
