8 Chapter 1: Introduction to the IDL Wavelet ToolkitDenoise ToolThis widget tool enables you to denoise your vector or image array by thresholding(hard or soft) either by cumulative power or coefficient number.Dataset ViewerManage the datasets within each project by importing new data, viewing data values,and customizing the data fields.Import DataYou can import data from a variety of file formats: ASCII, binary, image (BMP,JPEG, PNG, PPM, SRF, TIFF, DICOM), and WAV audio. Image files can be eitherindexed color (8- or 16-bit) or TrueColor (24-bit). You can also import data directlyfrom the IDL> command prompt.User ToolsYou can extend the functionality of the IDL Wavelet Toolkit by adding your owntools.What Is the IDL Wavelet Toolkit?IDL Wavelet Toolkit
Chapter 1: Introduction to the IDL Wavelet Toolkit 9IDL Wavelet Toolkit ArchitectureFile OrganizationThe Toolkit consists of the following components:• Source (.pro) files in the wavelet directory;• A bitmaps subdirectory with button bitmaps;• The data subdirectory with sample data files;• The Online help manual in the IDL help directory;• The DLM (Dynamically Loadable Module) in the IDL bin directory.NoteYou are encouraged to view the source files for details on implementation andtechnique. You are also welcome to modify the source files, however, it is stronglyencouraged that you copy the files to your own directory first. By modifying theIDL !PATH variable you can ensure that your routines are compiled first. See“!PATH” (IDL Reference Guide) for more information.StructureThe IDL Wavelet Toolkit consists of three layers. The topmost layer is the WaveletApplet, which allows you to import data and wavelet functions, and access variousvisualization and tool routines. The middle layer is the set of compound widgets andwidget tools for visualization and analysis. These tools are accessible both from theWavelet Applet and from your own routines. The lowest layer are the wavelet API(application programming interface) that consist of the wavelet functions, the wavelettransform, and the import data routine.IDL Wavelet ToolkitIDL Wavelet Toolkit Architecture
