OpenCV 3 Computer Vision with Python Cookbook

How it works...

cv2.cornerHarris is OpenCV's function which implements, as follows from the name, the Harris corners detector. It takes six arguments: the first four arguments are mandatory and last two arguments have default values. The arguments are as follows:

• Single-channel 8-bit or floating-point image, on which corners are to be detected
• Size of the neighborhood window: it should be set to a small value larger than 1
• Size of the window to compute derivatives: it should be set to an odd number
• Sensitivity coefficient for the corners detector: it's usually set to 0.04
• An object where you can store the results
• The borders extrapolation method

The borders extrapolation method determines the manner of image extending. It can be set to ...
