The noises of image is effectively suppressed by restricted Laplacian sharpening algorithm. The edges of image after processing are distinct and the details are deserved.

受限拉氏锐化算法有效地控制了图像的噪声，使处理后的图像边缘更加清晰，又保护了图像的细节。

Some image processing operations, like sharpening, make quality of noisy images even worse.

处理操作的一些图像，喜欢尖锐，用吵杂图像做成质量平滑的更坏事。

Since most image-processing operations, such as sharpening up a fuzzy document, or altering the colours in a photograph, involve looking at the value of a particular pixel and then altering it depending on the value of adjacent pixels, this is a real advantage.
