The sift package contains classes needed for wrapping and accessing the sift binary.
The binary itself is NOT included in this library as it is incompatible
with the licence. In order to use the SIFT algorithm, the binary has
to be obtained from the website.
Also, the path to the executable should be entered in the
jfeaturelib.properties
file.
The classes of this package should NOT be used directly except from the
according classes in the de.lmu.dbs.jfeaturelib.features
package.
