Export for LumiScan Training

Export for Training in the top bar downloads the annotated images as a ZIP file that is a complete LumiScan Training project: unpack it into the Training’s projects folder, open it there and start training. Reviewers and project admins see the button.

Exporting a project for LumiScan Training (no sound)

Settings

Project name in LumiScan Training

Name of the project folder and of its configuration file. Default: the project name.

Network type

The network LumiScan Training trains, for example ORTMXS (oriented, extra small, the Training’s default) or ORTMS. Can be changed in LumiScan Training later.

Validation %

Share of the images the training does not learn from but measures its progress on. Default 20.

Test %

Share kept for the final test. Default 0: LumiScan Training then tests on the validation images.

Keep each folder together

All images of a folder go to the same set. Use it when the images of a folder are a series of nearly the same scene: otherwise almost identical images end up in training and validation, and the validation figures look better than the network is.

Only the folder …

Export only the open folder instead of all.

Labels without orientation

Labels whose objects have no front or back (for example round washers): nonRotables in LumiScan Training.

Below the settings the dialog shows how many images and boxes go to each set, the classes, and how many images are left out because they have no annotation. Project admins' choices are kept as the project’s defaults for the next export.

Only images with an annotation are exported. With several annotators per image: the reference annotation (agreed or decided by a reviewer).
The annotation files are the same files the server stores (see Annotation Files).
The classes are the project’s labels in their order. Boxes labelled UNKNOWN, and boxes with a label that is not a class, are not learned; the info file counts them.
The configuration names the folders relative to the project (training, validation, test). LumiScan Training points them at the project folder when it opens the project.

The split stays the same

Which set an image belongs to is decided by its folder and file name, not by chance. Exporting the same project again, after more images were annotated, keeps every image in its set: an image the network learned from never becomes a validation image later, so the validation figures stay honest. Raising the validation share only moves images from training to validation.
