automatic detection of license plates as the first and most important step is the most intelligent traffic control systems, such as plaque Reader, the speedometer image processing and basic role in the mechanization of discovering violations of this section and the error reduction The overall results of these systems will be more efficient. In this context, this paper uses two different methods We compare lots of different images. The first method is to find the dimensions of the plaque, plaque, but the second method is based on Find the plaque is put together based on the character set. In the first method using a vertical Sobel operator and operator Morphology and try to find license plate frame in the input images and the second method uses the Laplace filter and combine it with techniques Morphological characters and eventually tries to find a license plate frame. In both methods to find the pixel density of an assay plate is used.
