Multimedia Forensics 2
They are as follows.
· Audio analysis.
Example of this field includes audio enhancement where some of the noise can be removed using
· Speaker identification.
The analysis involves voice comparison and one of the notable products in the market is BATVOX.
· Video analysis.
The video is break into frames for image enhancement. Some videos may need an analysis first to
improve the visual using special filters and techniques.
· Facial identification.
From the video and image enhancement, facial comparison can be analyzed and compared for
identification. Quintiliano et al.  introduced new algorithms called eigeneyes, eigenmouth and
· Photogrammetry and 3D modeling.
· Forensics linguistic.

It is quite interesting to know that our multimedia forensics capabilities in providing services are on par with the rest of the world.
