At the time, this was probably a pretty good book for explaining image processing on the PC. Given time, a large part of the book now has but historical value; the in-depth information on how to build your own digitalizer, with the awesome resolution of 640x480, with the option of grayscale or 256-color mode, is a touch useless. If you ever need to read a PCX file, the details are here; but when's the last time you saw a PCX file? However, some of the information has stayed useful; the description of the TIFF format hasn't changed much in the passing years, and there's a nice introduction to basic graphic processes, like tweaking contrast and edge-detection and other simple stuff.

I wouldn't suggest you run down a copy of this book, but having bought it for a couple bucks several years ago, it has served me in lieu of shelling out quite a few dollars on a modern book. ( )
