Development of ANPR Framework for Pakistani Vehicle Number Plates Using Object Detection and OCR

Table 5

Comparative analysis with previous ANPR methods based on Pakistani dataset.

ANPR methods	Vehicle types	Resolution	Localization technique	Character/plate recognition	Segmentation	Testing dataset	Overall accuracy/average score	Can be implemented in real time?
[20]	Car, bike, and bus	Medium	Vertical and horizontal histogram	OCR	Yes	50	93%	No
[21]	Only car	High (1140 × 641)	Edge detection	KNN	Yes	900	93%	No
The proposed ANPR	Car, bike, and bus	Low (416 × 416)	YOLOv3 or YOLOv4	OCR Tesseract	No	200	70% or 73%	Yes
