No really related, but I personally dislike GaussianBlur as the default noise removal method in all CV articles. In a lot of cases is more useful to filter by color (like BLACK letters in a white paper) otherwise bilateral filter (also available our of the box in OpenCV) usually works better especially if you want to do edge-detection (gaussian also blur edges). Yeah, GaussianBlur may be better performance-wise, but that is something you should consider if you real-time app is short of cpu-power. |
