Caliph & Emir 0.9.25 is mainly a maintainance release: There were some bugs in the content based image retrieval classes. Scalable Color descriptor extraction was fixed and yields now the same results as the MPEG-7 reference software. Furthermore ppm and bmp images are now supported. Note that Java 6.0 is required for the binary version and 1.5 for building it yourself.
The Scalable Color Descriptor was fixed: Now it matches the XM implementation (thanks to Fabrizio Falchi and Bastian Hoesch). EdgeHistogramImpl has also been updated according to a bug report & patch by Bastian Hoesch. Furthermore the DominantColor class was adapted based on suggestions by Janine Lachner. New feature is the support for ppm and bmp images.
Binaries, source and an installer for windows can be downloaded on sourceforge.net.
