Good reference, but not a good teaching book
Review written by: Stewart Trickett From
This book is a good reference for the Discrete Cosine Transform. The mathematics is only moderately difficult, and should provide little difficulty for a talented engineer graduate, say.

And yet I can't give this book a great review. It's all rather clinical, with little attempt to provide overview or insight. One just doesn't come away terribly enlightened.

The main reason provided as to why the DCT might be better than the DFT in some instances is that it is a more compact encoder of Markov sequences. Great, but what does this mean in practise? Well, the authors give many applications, but they are dealt with briefly, with little insight, and in a encyclopedic manner. Better would have been a few simple applications, done in more detail, where the authors made crystal clear why the DCT is the tool for the job.

I was hoping to come away with an in-depth understanding as to the properties of the DCT, where it's best applied, and why. I was disappointed.

This book is a must for people working in DSP fields
This book is so far the most complete reference of the transform "discrete cosine transform". We can see the author's time and effort by only looking at the reference section (more then 200+ references). This book outlines different algorithms for computing 1D, 2D DCT, IDCT, some includings FORTRAN codes. Without this book, collecting all the existing journals about DCT will probably takes several months. This book is good for novices about DCT, as well as good for experts.
