Automatic signature module

Every artwork image is checked for signatures and marks

The local engine detects and isolates candidate regions, searches the trusted mark library and runs conservative signature forensics. Optional AI interprets unreadable regions and creates research queries without changing the forensic verdict.

AI enrichmentLocal only

PipelineNot run

No automatic mark result yet

The module runs during normal analysis when a local image is available.

Marks laboratory

Isolate and identify signatures, hallmarks and maker marks

110 independent methods generate cleanup variants, stroke and symbol descriptors, library matches, trust controls and conflict warnings.

Open mark library

Signature forensics

Check consistency with known genuine variation

This does not declare a signature genuine. It measures fit against a multi-source reference set, confusing signers and natural variation.

No forensic check yet

Run mark matching first, then compare the questioned signature against a sufficiently broad trusted reference set.
