Abstract
We propose a straightforward intensity-based dissolve detection method which is able to cope with the particular constraints of the artistic animated movie domain. It uses the hypothesis that during a dissolve, the amount of fading-out and fading-in pixels should be high. Instead of just applying a global threshold, as most of the existing approaches do, we use a twin-threshold approach coped with shape analysis of the signal. This approach allows to reduce false detections caused by steep intensity fluctuations as well as to retrieve dissolves caught up in other visual effects. Experimental tests show that whether classic approaches tends to fail, the pro posed method provides a good detection even for very complex content setups (e.g. global movement, temporal discontinuity).
