The LIRE (Lucene Image REtrieval) library provides a simple way to create a Lucene index of image features for content-based image retrieval (CBIR), which allows searching for similar images. The used features are taken from the MPEG-7 standard: ScalableColor, ColorLayout, and EdgeHistogram. Furthermore, methods for searching the index are provided.


An issue where the scalable color descriptor (color histogram) was not compliant to the MPEG-7 standard was fixed. The color only search was changed to use the color layout descriptor and a bug in the edge histogram descriptor was hunted down. 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.
