Deep center-based dual-constrained hashing for discriminative face image retrieval

作者:

Highlights:

• A novel center-based deep supervised hashing framework integrating hashing learning and class centers learning for discriminative face image retrieval.

• Cluster intra-class samples into a learnable class center for intra-class variance reduction.

• Enlarge the Hamming distance between pairwise class centers for inter-class separability.

• Regression matrix to enhance binary codes compactness.

• State-of-the-art performance on four large-scale datasets under various code lengths and commonly-used evaluation metrics.
