该算法是通过计算图像功率谱大小来评价图像的清晰度。清晰的图像功率谱大于模糊图像的功率谱。(The algorithm is derived by calculating the size of the image power spectrum to evaluate the clarity of the image. Clear image power spectrum is greater than the power spectrum of blurred image.)

讲述PCM及13折线A率编码与解码的概念，随机给出一个语音信号，并用A率13折线的方法matlab编程对其编码与译码 (About the concept of PCM and 13 line-rate encoding and decoding A randomly given a voice signal and a line with a rate of 13 A method of encoding and decoding matlab programming for its)

说明：  在很多图像处理的过程中，需要判别一个图像的清晰度，和图像分割结果的优劣，于是就引出了信息熵的概念，绝大多数时候，它都被用来作为评价图像的一个量化标准。(In many image processing processes, it is necessary to distinguish the clarity of an image and the result of image segmentation, so the concept of information entropy is introduced. Most of the time, it is used as a quantitative standard to evaluate the image.)

通过修改图像像素值的后4低位比特，实现随机0～1序列水印信息的嵌入(Modify the four low bit， accomplish embedding random 0～1 watermark sequence. )
