Query: Facial Expression Recognition Under Partial Occlusion from Virtual
  Reality Headsets based on Transfer Learning   Facial expressions of emotion are a major channel in our daily
communications, and it has been subject of intense research in recent years. To
automatically infer facial expressions, convolutional neural network based
approaches has become widely adopted due to their proven applicability to
Facial Expression Recognition (FER) task.On the other hand Virtual Reality (VR)
has gained popularity as an immersive multimedia platform, where FER can
provide enriched media experiences. However, recognizing facial expression
while wearing a head-mounted VR headset is a challenging task due to the upper
half of the face being completely occluded. In this paper we attempt to
overcome these issues and focus on facial expression recognition in presence of
a severe occlusion where the user is wearing a head-mounted display in a VR
setting. We propose a geometric model to simulate occlusion resulting from a
Samsung Gear VR headset that can be applied to existing FER datasets. Then, we
adopt a transfer learning approach, starting from two pretrained networks,
namely VGG and ResNet. We further fine-tune the networks on FER+ and RAF-DB
datasets. Experimental results show that our approach achieves comparable
results to existing methods while training on three modified benchmark datasets
that adhere to realistic occlusion resulting from wearing a commodity VR
headset. Code for this paper is available at:
