Move

Overview

Moves images and videos, with their annotations, from one dataset to another. Assets that are already in the destination dataset are skipped.

Moved assets leave the source dataset. To keep them in the source, use Copy instead.

It’s handy for moving data out of a temporary or review dataset, for example to send rejected images back to labeling.

To move only part of the source, connect a second dataset to Assets to move (dataset), for example the output of Filter images. The node then moves only the source assets that this dataset also holds.

How it works

1

Takes the source images and videos. When an assets dataset is set, keeps only the ones it also holds.

2

Of those, finds the assets that the destination doesn’t have yet.

3

Moves each asset missing from the destination, together with its source annotations, in one step: an image never appears in the destination without its annotation, so a Labeling or Review step fed from the destination never hands out an unlabeled image.

4

Adds the source’s classes that the destination’s ontology doesn’t have yet.

FAQ

They’re skipped. The node doesn’t add them again and leaves them in the source dataset. Only assets missing from the destination leave the source.

Yes. Images and videos both move, and each asset’s annotations move with it.

The source dataset is empty, the assets dataset shares no assets with it, or every asset is already in the destination. Nothing moved in that run.

Not from a dataset version: Move changes both datasets in place and doesn’t create a new version of either. The assets aren’t deleted, so a Copy or Move in the other direction puts them back.

Inputs

From dataset
datasetRequired

Dataset to take the assets from. They leave it after the move. Key: SRC_DATASET.

To dataset
datasetRequired

Dataset to move the assets to, with their annotations. Assets it already has are skipped and stay in the source dataset too. Key: DST_DATASET.

Assets to move (dataset)
dataset

Dataset naming which assets to move: only the ones it shares with the source are moved. Leave empty to move everything from the source dataset. Key: ASSETS_DATASET.

Outputs

Destination Dataset
dataset

ID of the destination OvalBee dataset. Key: DST_DATASET.

Last Moved Assets Count
string

Short badge with the number of assets moved in the latest run. Shown on the node as a badge. Key: LAST_MOVED_ASSETS_COUNT.
