[1] Image Similarity Algebra
March 2017 Michael Loris
The Image Similarity Algebra for SECONDO provides operations to store
pictures in JPEG format into m-trees. It consists a ~Signature~ object
representing a the signature of a single JPEG image. The object is a
subtype of the Attribute class. The Image Similarity Algebra consists of
multiple files, including external files for k-means clustering.
