7.6 Examples
Wavelets have been used in countless applications, including many in the field of
biomedical image processing [27]. Using compactly supported wavelets that best
approximate the signal, the DWT provides a high-energy compaction relative to
other, traditional transform-based methods. Along with the energy compaction
property, the statistical properties of wavelet coefficients between scales or
within each subband [1, 28] provide objectively and visually superior results in
many applications, such as image compression, denoising, and image fusion.
7.6.1 Image Compression
Image compression is one of the most successful applications of the DWT. The
operation of a transform-based coder can be summarized in three steps. First an
image is transformed ...
