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.
