[1] Image Similarity Algebra
|
|
|

|
|
|
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.
