Movie and video scale-time equalization application to flicker reduction

Julie Delon

Résumé

Image flicker is a general film effect, which can be observed in videos as well as in old films, and consists of fast variations of the frame contrast and brightness. Reducing flicker of a sequence improves its visual quality and can be an essential first treatment before ulterior manipulations. This paper presents an axiomatic analysis of the problem, which leads to a global and fast method of "de-flicker", based on scale-space theory. The stability of this process, called Scale-Time Equalization, is ensured by the scale-time framework. Results on different sequences are given, and show a great visual improvement.
