Caliph and Emir: Lire 07 released

Java & MPEG-7 based tools for annotation and retrieval of digital photos and images, supporting semantic annotation and content based, meta-data based and semantic image retrieval. The sub project Lire offers a library for content based image retrieval.

Lire 0.7 is a major release fixing a lot of bugs and introducing several new features including new descriptor, a simplified way to use descriptors by introducing new generic searchers and indexers as well as an generalized interface for image descriptors. There are also several improvements in indexing and search speed (especially in autocolorcorrelogram). Furthermore retrieval performance was optimized based on the Wang 1000 data set. If you use Lire 0.7 to update an existing version, please make sure that your indices are created newly from scratch. All new features have also found their way into LireDemo, which now also supports multi-threaded indexing.
