Augmentation Restrictions

Augmentation restrictions prevent selected training transformations from being applied to an observation. Use them when a flip, rotation, movement, or scale change would make that sample incorrect or move an object outside the useful image area.

Restrictions apply to individual image or video observations. They complement the augmentation settings in Model Configuration: the model defines which augmentations are available, while each observation can exclude unsuitable ones.

Add or remove restrictions​

Select one or more observations, right-click a result, and open Restrict augmentations. Choose a restriction group, then select an item to add it to every selected observation. Selecting an item that is already present on all selected observations removes it.

Available restrictions depend on the active model and include controls for rotation, horizontal and vertical flips, scaling, movement, brightness, contrast, saturation, and hue. Rotated-box models can also keep selected boxes axis-aligned during rotation augmentation.

Calculate restrictions from boxes​

Choose Restrict augmentations > Calculate restrictions to derive restrictions from the selected observations' box positions.

  • Set a margin to keep augmented boxes away from image edges.
  • Include rotation and movement checks when those transformations must keep boxes in frame.
  • For rotated-box models, optionally keep affected boxes axis-aligned.
  • Use the reset option to replace existing restrictions instead of adding to them.

Calculation skips observations that do not have usable boxes. Progress is shown while larger selections are processed.

Choose Restrict augmentations > Reset to clear every restriction from the selected observations.

Filter observations​

Open Image filters > Augmentations to filter the current index results.

  • Include shows observations containing any selected restriction.
  • Exclude hides observations containing any selected restriction.
  • None shows only observations without restrictions.

Choose the restrictions, then select Apply. Use All in the Image filters menu to clear active filters.

Show restrictions in image information​

Turn on image information, then open Info shown and enable Augmentation restrictions. The overlay and tooltip list the readable restriction names assigned to each result. Disable this item when you want a less detailed overlay.

Export and import​

Observation restrictions are included when an index is exported and restored when it is imported. This works for both single-index and multi-index transfers. Older exports that do not contain restrictions remain supported.
