Nowadays there exist online image repositories containing hundreds of millions of images of all kinds of quality, size and content.

These image repositories grow day by day making techniques for navigating, indexing, and searching prudent. Currently indexing is mainly based on manually entered tags and/or individual and group usage patterns. Manually entered tags, however, are very subjective and not necessarily referring to the shown image content. This subjectivity and ambiguity of tags makes image retrieval based on manually entered tags difficult.

In this project we employ the image content as the source of information to retrieve images and study the representation of images by topic models. The developed approaches are evaluated on real world, large scale image databases.
