Until recently, filming has been an analogue
process; it requires a mechanical process to record and view, and
the source material itself is prone to decay & abrasion . Film is
expensive to store, and prohibitively expensive to restore. All
footage - historical, documentary or entertainment – may
completely degrade over time. While many archival films stocks
are currently being scanned and further damage thus prevented,
the digital copies are far from the quality of the original. The
types of aberrations found are varied, from frame jitter and line
scratches to dirt and sparkle. It is the detection of the latter two
(which are frame based abnormalities) that will be examined
