Indexing presentations using multiple media streams

This thesis presents novel techniques to index multiple media streams in a digi-
tally captured presentation. These media streams are related by the common content in
a presentation. We use relevance curves to represent these relationships. These relevance
curves are generated by using a mix of text processing techniques and distance measures for
sparse vocabularies. These techniques are used to automatically detect slide boundaries in
a presentation. Accuracy of detecting these boundaries is evaluated as a function of word
error rates.
