The Illusion of Super Resolution in OCR Systems The latest trend in license plate recognition systems is the use of super resolution pre filters to upscale blurry images before feeding them into Optical Character Recognition (OCR) models.
Proponents claim that these filters can take a low resolution image and transform it into a crisp, readable one, greatly improving accuracy. However, this approach might be nothing more than an illusion.
In the early days of Automated License Plate Recognition (ALPR), image preprocessing was used to enhance readability on specific camera setups.
