Shot transition detection using a perceptual distance function

A shot transition occurs when a frame fails to maintain perceptual continuity with its previous frame. To maintain perceptual continuity, two consecutive frames must contain similar perceptual features. We propose using the dynamic partial function (DPF) as the inter-frame distance function to detect perceptual discontinuity, and hence the boundary of a shot. Through analysis and experiments, we show that DPF is more effective than traditional distance functions for detecting shot transitions. We also discuss the foundation of DPF in cognitive psychology.
