Abstract

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 pair-wise 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 various indexing techniques.
