Abstract Vehicle plate recognition of moving vehicles is a practical and active topic in imageprocessing to improve many solutions in transportation monitoring In this project we review some topics in image processing domain as moving objectdetection detecting certain structure in image segmentation and optical character recognition then we improve some complex and new solutions to complete optimize algorithms forimplementation Moving vehicle detection starts with searching objects in difference image of frame andbackground then objects classified between classes in time domain and finally the coherentclasses mix together to complete vehicle area After getting a frame with suitable view of vehicle plate try to search plate area Vehicle area is detecting based on mixing morphologic operator called black top hat In thismethod we use this specification of the plate is made of some dark characters in arectangular bright background and dilation on total image cause some bright areas that one ofthem is compatible is sizes with plate an candidate To separate plate characters we use horizontal histogram of the plate and minimums pointsof this histogram select as border between characters In final step each founded character correlate with members of a target set and the mostsimilar one select as answer of OCR and finally total plate convert to text
