Why does extra sharpening make readable plates harder for OCR?
Answered by ANPR AI·Sourced
Short answer
Artificial enhancement can distort character boundaries.
Explanation
Edge and contrast processing may create misleading outlines.
Things to check
- Sharpening
- Contour enhancement
- Compression
What to do
Reduce enhancement and compare original plate crops. Tune for stable character detail rather than a visually dramatic surveillance image.
ANPR Edge
Skip the dedicated ANPR camera. Read plates from the cameras you already have.
ANPR Edge is plate-recognition software that runs on a PC at your site and works with ordinary IP cameras, so plate reads no longer depend on one vendor's camera, NVR or firmware.
- Works with standard IP cameras over RTSP
- One license per location covers every camera
- Runs on a Windows PC or Mac you own
