Focusing on offering an accurate and convenient evaluating method in edge-location algorithms, it first presents the method to obtain gray value of elliptical shape edge based on square aperture sampling, then convolutes the image with a Gauss filter and adds noise to the pre-processed image with the same intensity calculated in real image.

针对评价边缘检测算法精度时没有合适的评定标准的问题，首先根据方形孔径采样定理，详细说明了椭圆形状边缘灰度的求取方法，然后以真实拍摄图片为标准，对图像进行了高斯模糊和噪声的添加，形成最终的模拟图像。

The results showed that the fibers of Optim cloth have fewer crimps, the shape of the fibers becomes from elliptical to somewhat polygonal, and the distance between scales of the wool fiber is enlarged. The Optim cloth has a compact structure, smaller average compressed thickness, larger intensity of reflection light and diffuse reflection light, stronger contrast gloss, and good luster and smoothness.
