Efficient Object Recognition Based Image Annotation (Pixtract)

With the widespread use of digital cameras, cheaper and cheaper storage devices and the increasing digitalisation of art collections and library archives the number of digital images is constantly rising. Along with this fact the desire for a fast retrieval of relevant documents at a later time is also emerging. This requires efficient search strategies and indexing techniques on the one hand and metadata enrichment of the images on the other hand. Because of the huge amount of documents the manual annotation of images is impossible. In recent years several new promising automatic object recognition concepts were proposed for this reason which are more or less generic oriented.
The objective of this project is to implement an automatic content-based image annotation. The concrete aim is to achieve a translation from image contents to textual descriptions. Therefore the feature-based search is cut off from the text-based search. The former is used to create image annotations in combination with new object recognition concepts, which efficiency has to be improved through data organisation, index structures and access paths. Upon the assigned annotations a traditional text-based search can be implemented with established text indexing methods. The application of multimedia data-mining has to be analysed too for dealing with these massive amounts of data. The crucial point is to design a management structure that allows future extensions or restructuring and also lists sufficient restrictions for efficient annotation of images based on their content.
