An effective methodology for dynamic 3D facial expression retrieval
作者：
Highlights：
• We illustrate a novel retrieval methodology for dynamic sequences of 3D face scans.
• We present a detailed evaluation of the introduced retrieval scheme.
• BU-4DFE and BP4D-Spontaneous data sets were used for experiments.
• Retrieval results are used to achieve unsupervised facial expression recognition.
• The presented results outperform state-of-the-art retrieval schemes.
