Lire is a nascent effort and based on a cursory overview a while back, IMHO was an over-simplified version of what a CBIR engine should be. They use CEDD (color & edge descriptors). Wouldn't work for the kind of applications I am working on - which needs among other things, Color, Shape, Orientation, Pose, Edge/Corner etc. OpenCV has a steep learning curve, but having been through it, is very powerful toolkit - the best there is by far! BTW the code is in C++, but has both Java & .NET bindings. This is a fabulous book to get hold of: http://www.amazon.com/Learning-OpenCV-Computer-Vision-Library/dp/0596516134, if you are seriously into OpenCV. Pls feel free to reach out of if you need any help with OpenCV + Solr/Lucene. I have spent quite a bit of time on this.
