Video Analysis and Generation via a Semantic Progress Function

This paper introduces the Semantic Progress Function (SPF), a one-dimensional representation that captures how semantic meaning evolves over time in video sequences. The SPF is computed by measuring pairwise semantic distances between frames using a pretrained embedder (SigLIP) and fitting a smooth curve via regularized least squares. Departures from a…
