Flip

Bases: MultiVariateAlbumentation

Flip an image either horizontally, vertically, or both.

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
