How Image Degradations Affect Deep CNN-based Face Recognition?
Face recognition approaches that are based on deep convolutional neural
networks (CNN) have been dominating the field. The performance improvements
they have provided in the so called in-the-wild datasets are significant,
however, their performance under image quality degradations have not been
assessed, yet. This is particularly important, since in real-world face
recognition applications, images may contain various kinds of degradations due
to motion blur, noise, compression artifacts, color distortions, and occlusion.
In this work, we have addressed this problem and analyzed the influence of
these image degradations on the performance of deep CNN-based face recognition
approaches using the standard LFW closed-set identification protocol. We have
evaluated three popular deep CNN models, namely, the AlexNet, VGG-Face, and
GoogLeNet. Results have indicated that blur, noise, and occlusion cause a
significant decrease in performance, while deep CNN models are found to be
robust to distortions, such as color distortions and change in color balance.Comment: 8 pages, 3 figure
