基于matlab对灰度图像的二值化自适应阈值的算法(Gray image binarization adaptive algorithm)

数字信号处理(matlab版)随书源代码，作者维纳K英格尔，柳树堂译，本书提供大量的数字信号处理matlab程序，讲解数字信号处理知识，使得学习很容易上手(Digital signal processing (matlab version) source code with the book, the author Wiener K Ingle, Liushu Tang translation, the book provides a large number of digital signal processing matlab program, explain the knowledge of digital signal processing, makes learning very easy to use)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

image and signal processing are used mostly right now. these programs is related to image processing. Image negative is used for the getting the negative image of the original image. and contrast stretching is for the give the middle value. Fast Fourier Transform program is used for the getting FFT of the signal.
