Super Resolution Pre Filters in LPR OCR: A Misguided Trend The use of super resolution pre filters in Line Printer Recognition (LPR) Optical Character Recognition (OCR) has gained significant traction, but upon closer inspection, this trend appears misguided.
The application of deep learning based pre filters for super resolution can be detrimental to the overall performance of LPR OCR systems.
Understanding Super Resolution Pre Filters in LPR OCR Super resolution pre filters are designed to enhance low resolution images by upscaling them to a higher resolution.
