Emir is a free and open source, metadata based image retrieval tool that supports retrieval in file system based photo repositories created with Caliph.
Different types of retrieval mechanisms are supported:
· Content based image retrieval using the MPEG-7 descriptors ColorLayout, EdgeHistogram and ScalableColor.
· Keyword based searching using the Lucene search engine.
· Graph based retrieval supporting wildcards for semantic relations and semantic objects.
· 2D data repository and result set visualization based on FastMap & FDP algorithms.
Here are some key features of "Emir":
Retrieval of annotations using the file system:
· with XPath queries
· with keyword queries
· with quality constraints
· with example images for content based image retrieval
Retrieval of Annotations using a Lucene index:
· with inbuilt index creation
· using different fields for structured retrieval
Retrieval of semantic graphs based on a Lucene powered index:
· supporting wildcards for relations and nodes
· based on query expansion
· graphical query editor
2D data repository visualization based on FastMap and FDP algorithms:
· for image content descriptors ColorLayout, ScalableColor and EdgeHistogram
· for graphs based on the minimum common sub graph metric
Requirements:
· Java 1.5 or later
