HIPR2 contains many useful tutorials. These are contained in static web pages, which are VERY informational, as well as interactive JAVA applets which will be described later, by Stephen Hughes. The worksheet overview is: How to Use the Worksheets. Generally, there are nine categories of important image processing operations. Within each category, they are arranged in order of increasing difficulty. Each operation has these parts: Common name (and alternatives), Brief Description, How it Works, Guidelines for Use (with Imagelinks, which expand to full size pictures), Common Variants, Exercises (using the Image Library!), References, and Local Information (directions for your own local copy). Beyond this, difficult concepts may be cross-referenced to other files or supported by the glossary (The A to Z) or bibliography.
