et al.

Abstract: TrOCR, a recently proposed object character recognition engine, is implemented along with the YOLOv11 object detector into an Automatic Number Plate Recognition (ANPR) pipeline to identify plates at an entrance of one of the Universidad Juárez Autónoma de Tabasco campus. First tests show moderate results of TrOCR, obtaining a performance of 0.4605 using the Character Error Rate (CER) metric. To improve this result, we perform a fine-tune of the base TrOCR engine retraining the model using a dataset of 651 cust… Show more
