From video shot clustering to sequence segmentation

Segmenting video documents into sequences from elementary shots to supply an appropriate higher level description of the video is a challenging task. This paper presents a two-stage method. First, we build a binary agglomerative hierarchical time-constrained shot clustering. Second, bused on the cophenetic criterion, a breaking distance between shots is computed to detect sequence changes. Various options are implemented and compared. Real experiments have proved that the proposed criterion call be efficiently used to achieve appropriate segmentation into sequences.
