| Abstract | The objective of this project was to develop a computer system which is automatically capable of localization, segmentation and recognition of a Thai license plate from a video file. The system was called "Thai license plate recognition system" or "TLPRS". The TLPRS consisted of 5 modules, which were 1) video image acquisition, 2) license plate localization, 3) character segmentation, 4) character recognition, and 5) result presentation. The experiment was conducted on video files and localized car license plates from video frames in every second. After that the system segmented each character and recognized it. The experiment was conducted on video files with total length of 2.5 hours, which consisted of 497 car images. Based on the experimental results, the precision rate of license plate localization was 91.95 percent, while the character segmentation rate was 64.19 percent and the character recognition rate was 93.26 percent. |
