Abstract

We propose a multi-scale and multi-modal analysis and processing scheme for audio-video data. Using a non-linear scale-space technique audio-video is analyzed and processed such that it is invariant under various imaging and hearing conditions. Degradations due to Lyapunov and structural instabilities are suppressed by this scale-space technique without destroying essential semantic relations. On the basis of an audio-video segmentation its arrangements are quantified in terms of spatio-temporal inclusion relations and dynamic ordening relations by means of scaling connectivity relations. These relations infer a topological structure on top of the audio-video scale-space inducing a unimodal and multi-modal semantics. Our scheme is illustrated separately for video, audio and audio-video material the latter pointing out the added value of integrating audio and video.
