In that case, I'm afraid I'm short on suggestions, never having delved much beneath the "visible surface" of that sort of compression. Sorry!

I have looked at reviews of both books and feel they both have shortcomings. I notice that Richardson has a new version coming out soon which may well address some of the complaints. There seem very few up to date books on the subject to choose from. Many thanks. |
