| Abstract: | A dual-core DSP Blackfin561 embedded license plate recognition system is introduced. The hard- ware structure and software flow, as well as the neural network-based license plate recognition Hpofield methods and processes are discussed. The f video image is decoded to obtain the brightness of the image signal, then the image is processed such as adjustment, positioning, and segmentation; and finally, Hopfield neural network is used to iden- tify the license plate character information. |
