Functions

match_single()

Find the best match of a template in an image.

match_multiple()

Find all matches of a template in an image above a certain threshold.

cv2ext.template.match_multiple(image: ndarray, template: ndarray, method: int = 5, threshold: float = 0.8) → list[tuple[int, int, int, int]][source]

Find all matches of the template in the image.

Parameters:

  • image (np.ndarray) – The image to search for the template in.

  • template (np.ndarray) – The template to search for in the image.

  • method (int) – The method to use for template matching. One of cv2.TM_*. Default is cv2.TM_CCOEFF_NORMED.

  • threshold (float) – The threshold to use for matches. Default is 0.8.

Returns:

A list of tuples containing the x1, y1, x2, and y2 coordinates of the matches.

Return type:

list[tuple[int, int, int, int]]

cv2ext.template.match_single(image: ndarray, template: ndarray, method: int = 5) → tuple[int, int, int, int][source]
