What is the difference to the desktop tool LumiScan Annotation?

Annotation Web is its browser version and successor: a server on Windows 11 or Ubuntu 24.04 holds the images and annotations, and annotators work in Chrome, Edge or Firefox from any PC in the company network, without installing anything. Both write the same files, so the desktop tool can keep working on the same project folder.

Can several people annotate the same image?

Yes. In a project with several annotators per image, each annotates independently without seeing the others’ boxes. The server compares them, writes the reference annotation when all agree and shows reviewers the numbered differences to decide with one click. Agreement statistics show how consistent the annotators are.

Does LumiScan Training read the files unchanged?

Yes. The CSV and JSON files next to each image are byte-identical to those of the desktop tool. With several annotators, only agreed or reviewed boxes are written there.

How do box suggestions work?

An optional service runs your trained LumiScan networks (ONNX) – or an open-vocabulary detector for parts without a network yet – and proposes boxes that you accept, correct or discard. With active learning, the images the network is least sure about are annotated first.

Do images leave the company network?

No. The server, the project folders or S3 buckets and the box suggestion service all run on your computers; only your users’ browsers access them.

How do users sign in?

With local accounts, the company directory (Active Directory / LDAP) or single sign-on via OpenID Connect, for example Keycloak or Microsoft Entra ID. Roles – annotator, reviewer, project admin, server admin – are enforced by the server.

LumiScan Ecosystem: LumiScan Engineering

LumiScan Annotation Web

Annotate training data in the browser – as a team, with quality checks and box suggestions from your own networks.

LumiScan Annotation Web creates the training data for neural networks that detect and locate objects, for example for LumiScan AI Object Matching or LumiScan VGR. It is the browser version and successor of the desktop tool LumiScan Annotation: a server on Windows or Linux holds the images and annotations, and annotators work in their web browser from any PC in the company network, without installing anything.

Several annotators can annotate the same image independently. The server compares their boxes, writes the reference annotation when they agree and shows reviewers where they differ. Box suggestions from your trained networks speed up the work, and the annotation files are exactly those of the desktop tool, so LumiScan Training reads them unchanged.

Annotating

Oriented boxes as center-line rectangles in three clicks – moved, resized and rotated with mouse or keyboard
Magnifier with crosshair for edges to a tenth of a pixel
Labels on keys 1 to 9, brightness and contrast, region of interest
For image series: boxes from the previous image, copy and paste, box templates per label
Undo and redo, and a history of every saved state of every image

Working as a team

Projects with their own images, settings and members
Roles: annotator, reviewer, project admin and server admin
Sign-in with local accounts, Active Directory / LDAP or single sign-on (OpenID Connect)
Edit locks and revision notes from reviewers to annotators

Quality and speed

Several annotators per image, each without seeing the others' boxes
Automatic reference annotation when all agree; numbered differences for reviewers
Agreement statistics per annotator, per pair and per folder
Box suggestions from your trained LumiScan networks (ONNX) or an open-vocabulary detector
Active learning: the images the network is least sure about come first

Data and operation
