임계적으로 샘플링된 DWT
- Critically Sampled and Oversampled Wavelet Filter Banks
Learn about tree-structured, multirate filter banks. - Haar Transforms for Time Series Data and Images
Use Haar transforms to analyze signal variability, create signal approximations, and watermark images. - Border Effects
Compensate for discrete wavelet transform border effects using zero padding, symmetrization, and smooth padding.
