Objectives The purpose of this notebook is to give you a brief introduction to the DiscreteWavelets Toolbox and show you how to use it to load images. Some basic image manipulation is illustrated as well. You will also learn how to use measures and tools such as cumulative energy, entropy, PSNR, and Huffman coding. Help on the DiscreteWavelets Toolbox Help for the toolbox is available by clicking on Help and then Product Help (or press F1) and then clicking on the DiscreteWavelets Toolbox. Several demos and examples are available as well by clicking on the Demos tab on the Help menu. Image Basics The DiscreteWavelets Toolbox comes with 18 grayscale images and 9 color images for you to use. There are three functions available to tell you more about these images. The first function is called |ImageList|. This function can tell you the names and sizes of the digital images in the Toolbox.
