Use of a retrieval algorithm of keypoints in an information system ensuring the frame stability during digitization of archival film footage
Authors:A A Chertikhin  A I Vinokur
Abstract:One of the main technical tasks of any cinema archives-in which are deposited the movies as film footage-is the digitization of analog content to achieve two main goals, i.e. to provide a termless storage and a secure access to archival film footage Belousov, Vinokur and Vasin. The information contents stored as film footage are very large, many of the films are unique and don't occur in another form; and this storage method makes difficult their access and threatens their existence in unmodified state itself. The film degradation in form of medium shrinkage with aftermodification of geometry in the form of edges' shrinking, bending and bowing of the film surface, and destruction of the emulsion layer degrades the technical quality of the image, and leads to its complete loss. The data presentation in digital form eliminates this disadvantage and increases the accessibility of the film footage, allowing the selective access, including multimedia network, be it TV or Internet.
