Training more discriminative multi-class classifiers for hand detection

作者:

Highlights:

• A set of shared stumps are combined to strengthen the discrimination power of weak classifiers.

• A “slowest error growth” discriminant to determine the optimal combination of stumps.

• Multiple thresholds are leveraged in shared stumps to fit different classes.

• We associate effective features with different classes of hands, and employ mix-type features.

• As compared with JointBoost, our classifier can obtain a better classification performance with less runtime cost.
