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。

Experiments specify that we can get the accurate edge trace and the equations fitted from the collecting data through edge sharpening and detection of image processing technique.

实验结果表明，采用图像处理技术是可以将一个采集来的图像经过边缘锐化和边缘检测形成比较清晰的轨迹，能够拟合出比较精确的方程。

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.
