Tamura Features

[Andrea Ceroni]

Hi all,

I'm trying to extract Tamura textures by using the Tamura class. What I get as result is a vector of 18 elements (double), while I was expecting only three values (as specified in the description of the class). Does anyone know why so many values are extracted? And also, what's the meaning of each one of them?

Best,

Andrea

Hey Andrea,

thanks for using JFeatureLib.
I guess the 18 dimensions are caused by this part of the code in LIRE:
https://github.com/locked-fg/LIRE/blob/master/src/main/java/net/semanticmetadata/lire/imageanalysis/Tamura.java#L277

The array itself is filled a little later in
https://github.com/locked-fg/LIRE/blob/master/src/main/java/net/semanticmetadata/lire/imageanalysis/Tamura.java#L295
So element 0 should be the coarseness, 1 is contrast - followed by the
directionalities.

Hope this helps a little further.

Good luck!
Franz
