Detect corners🔗

Detects corners in images.


  • image: Input image.

  • threshold: Detection threshold. This value affects both the number of detections and the detection speed. A high value means only prominent corners will be detected. The lower the value, the more corners are detected, which also means lower processing speed.

  • radius: Distance between pixels in gradient computation. If the image zoomed up or down by a factor, the distance should be modified by the same factor.


  • image: Binary output image.

  • coordinates: The locations (x, y) of detected points in the world coordinate system.
