In alternating years, the Denver X-ray Conference turns its principal attention, through the choice of subjects for the plenary lectures, to various aspects of either X-ray fluorescence or dif- fraction. This is a "fluorescence" year, and the three invited lecturers are experts in techniques that are at, or perhaps yet a bit beyond, the forefront of our understanding and technology in that field. The common denominator in selecting these subjects was that each is approaching a full elucidation of theory, and active develop- ment of practical hardware, and that each presents analytical pos-...

The use of computer-based image analysis systems for all kinds of images, but especially for microscope images, has become increasingly widespread in recent years, as computer power has increased and costs have dropped. Software to perform each of the various tasks described in this book exists now, and without doubt additional algorithms to accomplish these same things more efficiently, and to perform new kinds of image processing, feature discrimination and measurement, will continue to be developed. This is likely to be true particularly in the field of three-dimensional imaging, since new...
