A new method for the automatic detection of blemishes on any kind of transparent photographic material (still and moving images, silver-based and dye-based material) is presented. It consists in an innovative combination of different optical techniques and computational photography. The image layer is a random dispersion of microscopic elements (e.g. silver particles in b&w material) and its interaction with light is isotropic. Dust, scratches and other irregularities of the film surface produce shadows and reflections that are strongly dependent on the provenance of light. The acquisition of multiple images with different geometries of illumination, and the analysis of the differences between them, is found to be an effective method to emphasize irregularities in the film surface. Moreover, the analysis with polarized light is found to improve the blemish detection. The experiments show that the innovative method effectively detects flaws on photographic film surface.", "abstract$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001457.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "authors": [ { "affiliation": "Imaging & Media Lab, Bernoullistrasse 32 - Basel CH-4056", "name": "Giorgio Trumpy" }, { "affiliation": "Imaging & Media Lab, Bernoullistrasse 32 - Basel CH-4056", "name": "Rudolf Gschwind" } ], "authors$meta": { "confidence": "high", "note": "Object form (schema 2.3.0) migrated from string form via migrateAuthorsToObjectForm.js; bio/affiliation backfilled from _source/SMPTE/HIGHWIRE/ NLM ++", "source": "parsed", "updated": "2026-06-23T00:04:25.562Z", "version": "authors-migrate-object-form@v1" }, "contentType": "orig-research", "contentType$meta": { "confidence": "high", "note": "Canonical-confirmed full paper (summary-abstract set is orig-research in the SMPTE canonical repos); HIGHWIRE-era abstract label was a delivery artifact", "originalValue": "summary-abstract", "source": "resolved", "updated": "2026-07-09T19:12:47.628Z", "version": "contenttype-fixes@v1" }, "copyright": { "holder": "Society of Motion Picture and Television Engineers, Inc.", "holder$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001457.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "year": "2012", "year$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001457.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" } }, "copyright$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001457.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docId": "10.5594-M001457", "docId$meta": { "confidence": "high", "note": "Derived from DOI 10.5594/M001457", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docLabel": "SMPTE Meetings and Conferences ( October 2012)", "docLabel$meta": { "confidence": "medium", "note": "Composed from venue title, volume/issue and date", "source": "inferred", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docTitle": "Computational Photography for Dust and Scratch Detection on Transparent Photographic Material", "docTitle$meta": { "confidence": "high", "note": "Parsed from NLM article XML (_source/SMPTE/HIGHWIRE/ORIGINAL SAMPLES/Conferences/smptem_2012_10/10.5594_M001457.xml)", "source": "parsed", "updated": "2026-05-22T21:44:19.125Z", "version": "smpte-conference-paper-nlm@v1" }, "docType": "Conference Paper", "docType$meta": { "confidence": "high", "note": "NLM
