Targets by Transform

Reference for data targets supported by Albumentations transforms.

Target Compatibility

Use these tables to check whether a transform updates images only or can safely update masks, bounding boxes, keypoints, volumes, and 3D masks.

Image-Only Transforms

Pixel-level transforms modify the image while leaving masks, boxes, and keypoints unchanged.

3D Transforms

Volumetric transforms operate on 3D volumes and the generated target columns they support.
