On Saturday morning Doug Cutting has announced the release of Lucene 2.0.0 on the mailing list: “[...] This is mostly a bugfix release from release 1.9.1. Note however that deprecated 1.x features have now been removed. Any code that compiles against Lucene 1.9.1 without deprecation warnings should work without further changes with any 2.x release. [...]” (Doug Cutting)
To Download Lucene visit the Apache download page. A detailed change log can be found here.
According to the mailing list the release for Lucene 2.0 for Java is scheduled for Friday, May 26th. Doug Cutting posted a vote for this date into the mailing list and no votes against this one followed. Main changes include that the APIs deprecated in v 1.9 are removed. So be prepared to update!
The LIRE library allows the creation of a Lucene Index for content based image retrieval (CBIR). Furthermore methods for searching the index are provided. In Lire 0.4 support for weighting has been added to the image searcher module. With weighting the importance of texture, colour and colour distribution for image retrieval can be specified. The new feature is described in detail in the online documentation and the API docs.
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.
I just uploaded the new Emir demo video. Now the video features the shiny JGoodies Look and not the crappy original Java style any more. To play it you will need a Flash player and this link, or just click it in the menu on the right hand side.
Furthermore the Caliph demo has also been updated, it’s now shorter than the old one but also reflects the latest changes.
The Caliph & Emir 0.9.22 release brings some whole new and configured metrics for result and repository visualization. The Suffix Tree Graph Metric has been tuned and evaluated, the BM-25 weighting scheme has been applied to path based graph comparison. Furthermore Lucene, Looks and Metadata-Extractor libraries were updated and some small issues were resolved.
An update to the famous and fine art of JGoodies is available: On May 2nd the Looks library in version 2.0.2 was released. An overview on the changes is given in the change log. The download is available here.
Today I checked the site of Drew Noakes and found out, that the metadata-extractor, the nice little and handy utility to extract EXIF and IPTC data from JPEG images in Java, has been updated to version 2.3.1. There is only one small bug fix in the class ExifDescriptor.java, rest remains the same (see the change log for more details). You can get it here.
When you browse through the photos (as shown in above screenshot) you will find a small find similar link on the topo right of the browser window. Using this you will get all images visually similar to the current one. One more hint for visiting CorvusAlbus: Don’t go there with MS Internet Explorer, it won’t help you much! Only FireFox, Opera and Konqueror are supported.
