**albumentations_experimental.augmentations.transforms.FlipSymmetricKeypoints**

Flip the input horizontally around the y-axis.

**Parameters:**

Name | Type | Description |
---|---|---|

`p` |
`float` |
probability of applying the transform. Default: 0.5. |

`symmetric_keypoints_horizontal` |
`tuple, list, dict` |
tuple of pairs containing indices of symmetric keypoints. Keypoints are considered as symmetric if horizontal flip swaps their semantics, e.g. left arm - right arm. If keypoint does not have pair then set as it is own index. Kyepoints length must be divisible to symmetric count. For example 5 symmetric pairs and 15 keypoints. |

`symmetric_keypoints_vertical` |
`tuple, list, dict` |
tuple of pairs containing indices of symmetric keypoints. Keypoints are considered as symmetric if vertical flip swaps their semantics, e.g. top corner - bottom corner. If keypoint does not have pair then set as it is own index. Kyepoints length must be divisible to symmetric count. For example 5 symmetric pairs and 15 keypoints. |

`symmetric_keypoints_both` |
`tuple, list, dict` |
tuple of pairs containing indices of symmetric keypoints. Keypoints are considered as symmetric if vertical and horizontal flip swaps their semantics, e.g. top left corner - bottom right corner. If keypoint does not have pair then set as it is own index. Kyepoints length must be divisible to symmetric count. For example 5 symmetric pairs and 15 keypoints. |

Targets: image, mask, bboxes, keypoints

Image types: uint8, float32
