消除噪声

The picture noise, invisible sensation, is usually distinctly different from its adjacent picture dots, performing to be white plague on black matrix or dark spots on white area. This noise influences the image's visual effect and relevant processing operation. Thus it is acquired to eliminate the noise of the picture.
