 Automatic number number plate recognition recognition From Wikipedia, the free encyclopedia

The system must be able to deal with different styles of license of license plates

License-plate recognition process

They can use e"isting closed-circuit teleision or road-rule enforcement cameras, plates cameras, or ones specifically designed for the task! They are used by b y arious police forces and as a method

of electronic electronic toll collection on collection on pay-per-use roads and roads and cataloging the moements of traffic or indiiduals!  #$%& can be used to store store the images captured by the the cameras as well as the te"t te"t from the license plate, with some configurable to store a photograph of the drier!
