“…Otherwise, if the bandwidth is good, the two bounds of the signal with this bandwidth are taken as a digit segment, and the function is recursively called for the part of the image which is at the right side of the digit segment just found. This is done until the whole width of the picture has been passed over [1,2].Once this segmentation has finished, the method keeps in the result only segment for which the area of the smallest rectangle containing them is more than MIN_AREA; then, it keeps only the seven segments in the result with largest area, and in case less than seven segments were found, it attempts to recall the whole method, after making the separation between the already found segments clearer (by cleaning the bits which are there) [3,4,5].License plates have always clear signature which corresponds to strong white level variations at somehow "regular" intervals. Due to noises, the variations are not always ideal and our algorithm permits to repair those variations.…”
