Feature Extractors
DCTR
Low complexity (FAST) features extracted from DCT residuals.
ZIP (for Windows) and TAR (for Linux) files contain C++ source code and Matlab MEX makefile.
Extraction using the MEX file is even faster.
PHARM
PHARM feature project in ZIP (for Windows) and TAR (for Linux) contains C++ source code and Matlab MEX makefile.
Extraction using the MEX file much faster.
Important: Implementations for different systems (Matlab, Windows, Linux) will output different feature values due to their random generators.
However, they should have identical performance.
GFR
JPEG Rich Model utilizing Gabor Filters.
