Résumé en anglais
A study on properties of data sets representing public domain audio
and visual content and their relation to their indexability is presented.
Data analysis considers the pairwise distance distributions and various
techniques to estimate the true intrinsic dimensionality of the studied
data. One own alternative to dimensionality estimation is also presented.
These results are contrasted with the indexability results gathered using
indexing techniques M-Tree, LSH and hierarchical k-means tree.
