Deep label refinement for age estimation

作者:

Highlights:

• We propose a Label Refinery Network (LRN) with two concurrent processes: label distribution refinery and slack regression refinery.

• The proposed label distribution refinery adaptively estimates the age distributions without the strong assumptions about the form of label distribution. Benefiting from the constant refinery of the learning results, label distribution refinery generates more precise label distributions.

• To further utilize the correlations among different age labels, we introduce regression to assist label distribution refinery. Besides, we introduce a slack term to further convert the discrete age label regression to the continuous age interval regression.

• We evaluate the effectiveness of the proposed LRN on three age estimation benchmarks and consistently obtain the state-of-the-art results.
