Study Of Image Identification Method And System On ID Card Numbers

If we could make use of the technology of computer seeing and realize automatic recognition of identifying ID Card numbers,we should greatly improve the efficiency of ID Card administration.Presently,most recognition systems of ID Card numbers are based on scanner,but this systems cannot meet the demand of long and real time catching image.This text lucubrates theoretic about image manipulation and pattern recognition and sets up a integrated regnition system of identifying ID Card numbers.on CCD Vedic.Concretery consist:(1)Firstly investigating the segmentation about image of illumination asymmetry.Due to a dotal lamp-house,the illumination of ID Card numbers image is asymmetrical. Therefore, the image segmentated by a only threshold is not effective on numbers recognition.This text exerts mathematical morpholoy methods on this image and commendably eliminates illumination asymmetry of image.The image after processing by mathematical morphology methods passes throught segmentation by a only threshold and is effective on numbers recognition.This text brings forward a method-relative brightness value processing,the method eliminates illumination asymmetry of image,thins hues of numbers and boosts up the contrast between lines of numbers and background.The image after processing by mathematical morphology methods passes throught segmentation by a only threshold and is effective on numbers recognition.(2)Secondly the image after segmentation has many small grains.Lines of numbers might connect short lines and might take place breakpoints.Therefore binary image need amendment.This text adopts the tracking contour method of tracking contour by which grains areas is calculated and is well wiped off small grains.(3)Thirdly locating numbers'position.The position of numbers is not fixed and must be live made sure.Aimming at shortcoming of projection method,this text put forward a new method of traversing distance by which makes certain the position of numbers.the position made sure is well and truly.(4) Fourthly recognizing ID Card numbers.The recognition based on configuration classifying.This text put forward a new method by which arc and circularity are recognise.this method is operationally simple ,well-marked and greatly satisfy the request of accurate recognition.This text by the numbers and across-the-board studys the recognition system of identifying ID Card numbers based on CCD vidicon and realizes fast recognition for identifying ID Card numbers.This text studys by the numbers and across-the-board the makeup and recognizing methods of the recognition systeraThis text builds up a integrated recognition system of identifying ID Card numbers.
