Approximately symmetrical face images for image preprocessing in face recognition and sparse representation based classification

作者:

Highlights:

• Developed a novel method to automatically produce approximately axis-symmetrical virtual face images.

• Treated as an effective image preprocessing method.

• Used as a virtual image dictionary learning method for image classification.

• Extensive experiments on different face databases show its effectiveness as an image preprocessing algorithm.

• The strong identification capability of our method is verified in comparison with state-of-the-art dictionary learning algorithms.
