Combined sparse and collaborative representation for hyperspectral target detection

作者：

Highlights：

• A combined sparse and collaborative representation-based detector is proposed.

• Target detection can be achieved by evaluating the difference of the two residuals.

• Residuals are from target sparse representation and background collaborative one.

• The background collaborative representation is enhanced by a Tikhonov regularization.
