Milan Leads Europe on Duplicate Image Removal — But Rivals Are Closing Fast

Milan's digital archive managers are confronting a problem that has grown faster than anyone predicted: the proliferation of duplicate images flooding municipal databases, fashion industry asset libraries, and publicly funded cultural platforms. The city's response has been more systematic than most European peers, though the gap is narrowing.

The issue is immediate. With the Milan-Cortina 2026 Winter Olympics now months away, city agencies are racing to clean promotional and archival photo libraries before the global broadcast window opens. Organising committee staff at the Fondazione Milano Cortina 2026 have been working since January to audit thousands of accreditation, venue, and promotional images, after early-stage reviews revealed significant duplication rates in shared media portals — a problem common to multi-agency events where dozens of contractors upload independently.

Why Milan Is Taking This Seriously Now

The practical cost of ignoring duplicates is real. Storage redundancy across large municipal image repositories can inflate cloud infrastructure bills by 20 to 30 percent, according to general benchmarks from enterprise data management research published by Gartner in 2025. For institutions handling tens of thousands of assets — common in Milan's fashion and design economy — that figure compounds quickly. The Camera Nazionale della Moda Italiana, which coordinates digital assets across dozens of member brands concentrated around Via Montenapoleone and Corso Como, began piloting automated deduplication software in the second quarter of 2025. The pilot covered roughly 400,000 archived runway images from shows between 2019 and 2024.

The Comune di Milano's own digital services directorate, operating under the broader Piano Digitale framework adopted in 2023, set a target of reducing image redundancy in public-facing databases by 40 percent before the end of this year. Two Porta Nuova-based tech firms — both tenants in the UniCredit Tower complex — are among the contractors supplying the hash-matching and perceptual-similarity tools being evaluated for that contract.

The Pinacoteca di Brera took an earlier lead. The gallery began digitising and deduplicating its photographic archive in partnership with the Istituto Centrale per il Catalogo e la Documentazione in Rome back in 2022, creating a model that other Lombard cultural institutions have since cited as a template. By early 2026, the Brera project had consolidated over 60,000 image records, eliminating an estimated 18 percent duplication rate in the original dataset.

How Milan Compares to London, Amsterdam, and New York

London's approach has been patchier. The Victoria and Albert Museum completed a similar deduplication exercise on its digital collections in 2024, but the broader Greater London Authority has no unified standard across borough councils. Amsterdam's Rijksmuseum has set the benchmark most frequently cited by archivists: its open-access image programme, which made over 700,000 high-resolution works available online, built deduplication into the system architecture from 2019 onward, meaning duplicate problems are caught at ingestion rather than retrospectively. New York's Metropolitan Museum of Art similarly baked deduplication into its Open Access initiative, launched in 2017 and expanded continuously since.

Milan sits between those leaders and the laggards. It has the institutional will — especially with Olympics pressure providing a hard deadline — and a commercial fashion sector that cannot afford reputational damage from mis-tagged or repeated imagery in global lookbooks. But its public-sector coordination has historically been fragmented between the Comune, the Regione Lombardia, and individual cultural bodies, each running separate digital infrastructure. That jurisdictional tension, familiar in any city where centre-left municipal government sits alongside a centre-right regional administration, slows standardisation.

Practically, institutions and businesses in Milan dealing with large image libraries should audit their asset management systems before the fourth quarter, when Olympics-related digital traffic will spike sharply. Tools such as open-source perceptual hashing libraries — used by several Milanese design studios already operating out of the Tortona design district — offer a cost-effective starting point. The Camera della Moda's pilot results are expected to be shared with member brands in September 2026, giving smaller fashion houses a framework before the winter season campaign rush.
