资源描述图像去噪图像处理中的非局部均值算法。不同于“局部均值”的过滤器，它采取的平均值的一组像素周围的目标像素的平滑图像，非局部均值滤波，以平均的所有像素的图像，加权类似这些像素的目标像素。这导致了更大的后过滤的清晰度，减少损失图像中的细节与局部均值算法比较。

       Dual Tone Multi Frequencies (DTMF tones) are two different tones at two ends of a spectrum that are used to send information in telephonic communication mediums. The tones represent numbers 0-9 and the symbols * and #. A series of these numbers may be assigned to individuals as points of contact, as in a phone number, or the numbers can be used to relay other sorts of information.       While it may seem confusing, it should be noted that all numbers on a telephone are assigned two DTMF tones, and in all, seven different frequencies are assigned. Some numbers will have the same lower frequency, but different higher frequency, while others will have the same higher frequency but a different lower frequency. The range is between 697 Hz and 941 Hz for the lower frequencies and 1209 Hz and 1633 Hz for
