Helper functions for working with keypoints (augmentations.core.keypoints_utils)

class albumentations.core.keypoints_utils.KeypointParams (format, label_fields=None, remove_invisible=True, angle_in_degrees=True, check_each_transform=True) [view source on GitHub]

Parameters of keypoints

Parameters:

Name	Type	Description
format	str	format of keypoints. Should be 'xy', 'yx', 'xya', 'xys', 'xyas', 'xysa'. x - X coordinate, y - Y coordinate s - Keypoint scale a - Keypoint orientation in radians or degrees (depending on KeypointParams.angle_in_degrees)
label_fields	list	list of fields that are joined with keypoints, e.g labels. Should be same type as keypoints.
remove_invisible	bool	to remove invisible points after transform or not
angle_in_degrees	bool	angle in degrees or radians in 'xya', 'xyas', 'xysa' keypoints
check_each_transform	bool	if True, then keypoints will be checked after each dual transform. Default: True

def albumentations.core.keypoints_utils.check_keypoint (kp, rows, cols) [view source on GitHub]
