给灰度图像任意着色，利用随机游走算法，色彩空间变换，通过YCbCr色彩空间完成图像着色(Any color to grayscale images using random walk algorithm, color space conversion, the YCbCr color space to complete the image coloring)

快速傅里叶变换 可以计算并且仿真出图片等，里面包括三角变换、逆变换等。(Fast Fourier Transform And simulation can be calculated, such as a picture, which includes the triangular transform, inverse transform and so on.)

说明：  OQPSK的调制解调程序，希望对初学的你有所帮助 (OQPSK modulation and demodulation process, you want to be helpful for beginners)

IMAGE_CONTRAST is a MATLAB function which carries out a simple contrast enhancement operation on an image. Note that MATLAB s image processing toolbox includes a functions such as nlfilter which can do a more sophisticated treatment of images. But the purpose of this example is to demonstrate the process of image enhancement in a way that is clear enough to understand quickly.
