A flexible transformation class for using user-defined transformation functions per targets. Function signature must include **kwargs to accept optional arguments like interpolation method, image size, etc: Args: image (Callable[..., Any] | None): Image transformation function. mask (Callable[..., Any] | None): Mask transformation function. keypoints (Callable[..., Any] | None): Keypoints transformation function. bboxes (Callable[..., Any] | None): BBoxes transformation function. p (float): probability of applying the transform. Default: 1.0. Targets: image, mask, bboxes, keypoints, volume, mask3d Image types: uint8, float32 Supported bboxes: hbb, obb Number of channels: Any
