Messy Canny edges? It’s usually not the algorithm — it’s the input. This video shows 3 quick fixes to clean up noisy edge detection: • Blur before applying Canny • Tune lower & upper thresholds (keep a 2:1–3:1 ratio) • Avoid over-compressed images Small tweaks, much cleaner edges ✨ Resources 📘 Learn OpenCV from scratch → https://vist.ly/4kvet #ComputerVision #OpenCV #ImageProcessing #CannyEdges #EdgeDetection
