Deep-feature encoding-based discriminative model for age-invariant face recognition

作者:

Highlights:

• A robust deep-feature encoding-based discriminative model for age-invariant face recognition is proposed.

• Our method learns high-level deep features using a pre-trained deep-CNN model (AlexNet), which are then encoded by learning a codebook, which converts each of the features into a discriminant S-dimensional codeword for image representation.

• A new feature-encoding framework based on locality constraint is proposed, which provides closed-form solutions in both encoding and codebook-updating process.

• Experimental results on three challenging face-aging datasets demonstrates the superiority of our proposed method.
