Rotate

Bases: MultiVariateAlbumentation

Rotate the input by an angle selected randomly from the uniform distribution.

Parameters:

Name	Type	Description	Default
mode	Union[None, str, Iterable[str]]	What mode(s) to execute this Op in. For example, "train", "eval", "test", or "infer". To execute regardless of mode, pass None. To execute in all modes except for a particular one, you can pass an argument like "!infer" or "!train".	None
ds_id	Union[None, str, Iterable[str]]	What dataset id(s) to execute this Op in. To execute regardless of ds_id, pass None. To execute in all ds_ids except for a particular one, you can pass an argument like "!ds1".	None
image_in	Optional[str]	The key of an image to be modified.	None
mask_in	Optional[str]	The key of a mask to be modified (with the same random factors as the image).	None
masks_in	Optional[str]	The key of masks to be modified (with the same random factors as the image).	None
bbox_in	Optional[str]	The key of a bounding box(es) to be modified (with the same random factors as the image).	None
keypoints_in	Optional[str]	The key of keypoints to be modified (with the same random factors as the image).	None
image_out	Optional[str]	The key to write the modified image (defaults to image_in if None).	None
mask_out	Optional[str]	The key to write the modified mask (defaults to mask_in if None).	None
masks_out	Optional[str]	The key to write the modified masks (defaults to masks_in if None).	None
bbox_out	Optional[str]	The key to write the modified bounding box(es) (defaults to bbox_in if None).	None
keypoints_out	Optional[str]	The key to write the modified keypoints (defaults to keypoints_in if None).	None
bbox_params	Union[BboxParams, str, None]	Parameters defining the type of bounding box ('coco', 'pascal_voc', 'albumentations' or 'yolo').	None
keypoint_params	Union[KeypointParams, str, None]	Parameters defining the type of keypoints ('xy', 'yx', 'xya', 'xys', 'xyas', 'xysa').	None
limit	Union[int, Tuple[int, int]]	Range from which a random angle is picked. If limit is a single int an angle is picked from (-limit, limit).	90
interpolation	int	Flag that is used to specify the interpolation algorithm. Should be one of: cv2.INTER_NEAREST, cv2.INTER_LINEAR, cv2.INTER_CUBIC, cv2.INTER_AREA, cv2.INTER_LANCZOS4.	INTER_LINEAR
border_mode	int	Flag that is used to specify the pixel extrapolation method. Should be one of: cv2.BORDER_CONSTANT, cv2.BORDER_REPLICATE, cv2.BORDER_REFLECT, cv2.BORDER_WRAP, cv2.BORDER_REFLECT_101.	BORDER_REFLECT_101
value	Union[None, int, float, List[int], List[float]]	padding value if border_mode is cv2.BORDER_CONSTANT.	None
mask_value	Union[None, int, float, List[int], List[float]]	padding value if border_mode is cv2.BORDER_CONSTANT applied for masks.	None
