This conclusion presents some closing thoughts on the concepts covered in the preceding chapters of this book. The book presents information to support the personalization by instructors of the materials presented. It utilizes one or more data sets from the collections of DICOM images that are available on the Web. Instructors can begin the session by giving examples from their own experience, which helps to bring points to life. The image could be supplied by the instructor, or be generated by the students using an image of a point spread function and the option for frequency domain convolution in ImageJ. A second motivation for using macros is that they can be used to allow students new to image processing to perform a realistic image processing protocol, without having to implement the protocol themselves. Plugins allow the user to implement their own functions and use them just like any of the built-in menu commands in ImageJ.
