Query: Single Morphing Attack Detection using Feature Selection and
  Visualisation based on Mutual Information   Face morphing attack detection is a challenging task. Automatic
classification methods and manual inspection are realised in automatic border
control gates to detect morphing attacks. Understanding how a machine learning
system can detect morphed faces and the most relevant facial areas is crucial.
Those relevant areas contain texture signals that allow us to separate the bona
fide and the morph images. Also, it helps in the manual examination to detect a
passport generated with morphed images. This paper explores features extracted
from intensity, shape, texture, and proposes a feature selection stage based on
the Mutual Information filter to select the most relevant and less redundant
features. This selection allows us to reduce the workload and know the exact
localisation of such areas to understand the morphing impact and create a
robust classifier. The best results were obtained for the method based on
Conditional Mutual Information and Shape features using only 500 features for
FERET images and 800 features for FRGCv2 images from 1,048 features available.
The eyes and nose are identified as the most critical areas to be analysed.
