Canny Edge Detector


Theory of Canny Edge Detector



Steps involved in 1-D Canny Edge Detector

  • Calculate Gaussian and derivative
  • Perform Gaussian smoothing on image
  • Convolve with Gaussian derivative
  • Find maxima

    • Some more points

  • One of the most effective algorithms in use today
  • Computationally intensive, but is robust in the presence of noise
