Abstract
This paper studies content-based video retrieval using the combination of audio and visual features. The visual feature is extracted by an adaptive video indexing technique that places a strong emphasis on accurate characterization of spatio-temporal information within video clips. Audio feature is extracted by a statistical time-frequency analysis method that applies Laplacian mixture models to wavelet coefficients. The proposed joint audio-visual retrieval framework is highly flexible and scalable, and can be effectively applied to various types of video databases.
