Blotch detection for digital archives restoration based on the fusion of spatial and temporal detectors
This paper proposes a method based on the Dempster-Shafer evidence theory for the detection of blotches in digitized archive film sequences. The detection scheme relies on the fusion of two uncorrelated fast, no motion compensated, spatio-temporal blotch detectors. The imprecision and uncertainty of botch detectors are modeled using Dempster-Shafer evidence theory, which improves the decision, by taking into acoount the …
Chasing Technology The Challenge of Preserving Audiovisual Records
Archivists who work with audiovisual records often find themselves confronting a challenge their counterparts who deal with traditional paper records do not have. They must often act as “bucket brigades”—chasing one “fire” after another as rapidly changing technology threatens to render the media formats storing audiovisual records obsolete and inaccessible. What these archivists face is the daunting task of preserving—and …
Digital Intermediate Format Choices, or: How many K’s do I need?
A short but to the point description of the choice for a 2K or 4K film scanning resolution, issued by IVC Digital Film Center.
MTS Pilot tracking algorithm for “wow”distortion
New algorithm for detection of the wow distortion characteristic basing on the MTS pilot tracking is introduced. By observing a variation of the pilot frequency, the depth of the parasitic modulation can be estimated. MTS is an audio coding system used in an NTSC television standard, thus the algorithm is applicable only in that type of recordings. It is based …
Hollywood’s Proposals for Digital Cinema. Digital Projection of Heritage Film Content at Original Frame Rates
Een voorstel van de technische commissie van de FIAF aan het SMPTE DC28 comité m.b.t. de toekomstige standaard voor digitale projectie van film in bioscopen. Biedt een overzicht van het DCI (Digital Cinema Initiative) voorstel en pleit voor meer flexibiliteit in de voorgestelde framerates. Deze publicatie is vooral van belang voor filmtechnici. Dit geldt in het bijzonder voor de twee …
