Chapter 2: Using the IDL Wavelet Toolkit 39Multiresolution Analysis in the WaveletToolkitMultiresolution Analysis uses the wavelet transform to decompose a data series in acascade from the smallest scales to the largest. At each scale there are threecomponents: the Smooth (or low-pass filtered) data series, the Details (or band-pass)data series, and the Rough (or high-pass).For one-dimensional vectors, this can be viewed as a hierarchy of x-y plots, as shownin the following figure:For two-dimensional arrays, the multiresolution analysis gives a series of images.File MenuPage SetupThis menu item sets up the page height and width for exporting and printing.Export PostscriptExport the image to a postscript file.Printer SetupThis menu item allows you to set up the printer via the Printer Dialog.PrintThis menu item prints the image.CloseThis menu item closes the Multiresolution viewer.Wavelet OptionsYou can change the current wavelet family, or the order.
