用matlab编程来提取图像的灰度共生矩阵(Extracting symbiotic matrix of the the image with matlab.GRAYCOMATRIX Create gray-level co-occurrence matrix)

说明：  五点三次平滑法可用作时域和频域信号平滑处理。对时域作用是减少混入振动信号中的高频随机噪声。对频域是能使谱曲线光滑。(Three five-point smoothing method can be used as time domain and frequency domain signal smoothing. Effect on the time domain vibration signals to reduce high-frequency mixed with random noise. On the frequency domain is the spectral curve can smooth.)
