Abstract: A system (100) and method for extracting and recognizing characters which are inscribed in a vehicle license plate image has been disclosed. The system (100) comprises an image analysing processor (102) for extracting the characters by binarizing the image in an iterative manner with a convergence property which prevents over enhancing of the binarized plate image. The processor (102) includes a binarization module (106) which selectively strengthens and weakens the license plate image's pixel intensity and thereby replaces them with any one of two distinct intensity values in the iterative manner till the binarized image reaches a converging state having an upper part with high intensity value, and a lower part with low intensity value and middle part with intensities that are unattainable to convert into high intensity value.
