Title
Harmonic convolutional networks based on discrete cosine transform
Abstract
•The harmonic block is designed to learn filter weights in the DCT domain.•Harmonic CNNs are constructed by replacing the convolutional layers.•Parameter learning in frequency domain improves performance.•High-frequency parameter truncation can efficiently compress new or trained CNNs.•The hamonic block can make a CNN invariant to illumination changes.
