A design of a brand new genetic algorithmic rule (GA) is introduced to detect the locations of the license plate (LP) symbols. An adaptive threshold methodology has been applied to beat the dynamic changes of illumination conditions once changing the image into binary. Open ALPR (Automated license plate Recognition) is used to observe candidate objects within the image. This methodology depends on distinctive the key characteristic of a number plate the concentration of characters with robust light-on-dark edges. The system that reads variety plates from any digital image, color or monochrome, sizes vary from 640×480 to megapixel pictures there are 3 major steps to number plate reading. Locating and analytic the amount plates within the image, Locating and isolating the characters within the number plate, Reading the characters (OCR, optical character recognition).
