用GUI编写的OFDM代码,编写质量高,是学习的好程序,内有doc详细解释。(prepared using OFDM GUI code, preparation of high quality, is a good learning process, there doc explained in detail.)

PROJECT 02-02 Reducing the Number of Intensity Levels in an Image (a) Write a computer program capable of reducing the number of intensity levels in a image from 256 to 2, in integer powers of 2. The desired number of intensity levels needs to be a variable input to your program. (b) Download Fig. 2.21(a) from the book web site and duplicate the results shown in Fig. 2.21 of the book.
