本程序实现全变分(Total Variation, TV)的去噪算法，它使用了PDF纠正TV算法中的小问题。该算法可以很好地保留原图边缘信息的同时，去除噪声。
-This procedure for full-variational (Total Variation, TV) denoising algorithm, which uses the PDF to correct TV algorithm small problem. This algorithm is well preserved, while Original edge information to remove noise.
