Abstract: We have studied a multi-frame image processing method for recognition of degraded car license plate images. In actual situations, various distortions such as geometric distortions or various blurs are imposed on recorded images. Therefore in order to apply the multi-frame image processing method to moving objects, it is necessary to correct geometric distortions. When images are blurred with out-of- focusing or motion blur, it is necessary to remove or suppress such distortions. In this report, we examined the geometric distortion correction and deblurring for multi- frame image processing and confirmed the effectiveness of the method. The example for real videotaped images is also shown in this report. As a result, it is recognized that the multi-frame image processing method is effective for recognizing characters on moving car license plates.!1
