LIRe 0.5.4 Released

In Lire 0.5.4 some bugs were fixed: The scalable color descriptor (color histogram) was not compliant to the MPEG-7 standard, which is now fixed. The color only search was changed to use the color layout descriptor and a bug in the edge histogram descriptor was hunted down.

Note that you have to re-index your files: Your old index cannot be used with the new version as 2 descriptors have changed. Furthermore all binary files have been compiled with Java 6.0. So if you need a Java 1.5 version you’ll need to recompile yourself (ant build file is included) and include the swing layout class library from NetBeans.

The LireDemo GUI application has also been updated: A new function for creating image mosaics has been introduced and the indexing of digital photos is now faster than ever as only the EXIF thumbnails - if available - are used instead of the whole image.

Go to the LIRe page for download links and further information.

Caliph & Emir v0.9.25 released

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.

It further includes library updates and a new demo mode (endless loop of iterative arrangement in visualization) in Emir.

Visualization Demo Video Online

The demo session on the 77th MPEG Meeting was quite a success, many people were interested in the visualization. Many talks about standardisation, surveillance and other things where visual analysis could be needed took place at the demo desk. After the demo session I was asked to record a video of the visualization of Emir. Well that was easy. I’ve published the video here, optional download here. >> Watch the video

Nice review on Caliph and Emir has been posted …

Within the digitizationblog at http://digitizationblog.interoperating.info/ a very nice review / pointer on Caliph & Emir has been published. About Caliph and Emir it was said that […] nicely illustrate a useful implementation of MPEG-7 […] and that there are very few tools showing actual power of MPEG-7, which is a statement I fully agree with.
