| Abstract: | A new system for localization and classification of images using FPGA and DSP is proposed In this paper, in order to solving the difficulties of accurate locating the license number plate , developing a portable system for image processing. At last, the designing method of the testing platform is given with comprehensive test data listed. Relevant experiments shows that the system throughput rate is within 15 frames per second when FPGA clock is 50 MHz, which has met the requirement for real time processing. |
