Image Fusion

This section takes you through the features of Image Fusion, one of the MATLAB Wavelet Toolbox specialized tools.

For the examples in this section, switch the extension mode to symmetric padding, using the command:

The Wavelet Toolbox requires only one function for image fusion: wfusimg. You'll find full information about this function in its reference page.

In this section, you'll learn how to

Since you can perform analyses either from the command line or using the graphical interface tools, this section has subsections covering each method.

The principle of image fusion using wavelets is to merge the wavelet decompositions of the two original images using fusion methods applied to approximations coefficients and details coefficients (see [MisMOP03] and [Zee98] in References).

The two images must be of the same size and are supposed to be associated with indexed images on a common colormap (see wextend to resize images).

Two examples are examined: the first one merges two different images leading to a new image and the second restores an image from two fuzzy versions of an original image.
