Discriminant DCT Feature Extraction
David D. Zhang, Xiao‐Yuan Jing, Jian Jun Yang · Computational intelligence and its applications (COMIA) book series/Computational intelligence and its applications series · 2006
This chapter provides a feature extraction approach that combines the discrete cosine transform (DCT) with LDA. The DCT-based frequency-domain analysis technique is introduced first. Then, we describe the presented discriminant DCT approach and analyze its theoretical properties. Finally, we offer detailed experimental results and a chapter summary.
