Two-Dimensional Discrete Stationary Wavelet Analysis

This section takes you through the features of two-dimensional discrete stationary wavelet analysis using the MATLAB Wavelet Toolbox. For more information, see Available Methods for De-Noising, Estimation, and Compression Using GUI Tools.

The Wavelet Toolbox provides these functions for image analysis. For more information, see the reference pages.

Analysis-Decomposition Function

Function Name	Purpose
swt2	Decomposition

Synthesis-Reconstruction Function

Function Name	Purpose
iswt2	Reconstruction

The stationary wavelet decomposition structure is more tractable than the wavelet one. So, the utilities useful for the wavelet case are not necessary for the Stationary Wavelet Transform (SWT).

In this section, you'll learn to

• Load an image
• Analyze an image
• Perform single-level and multilevel image decompositions and reconstructions (command line only)
• De-noise an image
