求翻译：一般的边缘检测算法是基于微分技术的算法, 如Laplacian 算子、Sobel 算子和Canny 算子等, 他们的边缘检测和定位精度仅能达到一个像素的精度, 并且微分算子对于噪声非常敏感, 常会产生一些伪边缘等.是什么意思？

The edge detection algorithm is based on the differential algorithm, such as the laplacian operator, sobel operator and canny operators such as edge detection and positioning accuracy can only reach a pixel accuracy, and the differential operator is very sensitive to noise, often produce some pseudo

In general the edge detection algorithm is based on the differential technology Laplacian algorithms, such as counting, counting Sobel Canny Sub and Sub as such, their edge detection and positioning accuracy can be achieved only by one pixel precision, and differential operator for noise is very sen

The general edge examination algorithm is based on the differential technology algorithm, like the Laplacian operator, the Sobel operator and the Canny operator and so on, their edge examination and the pointing accuracy only can achieve a picture element the precision, and the derivative operator i

General algorithm of edge detection algorithm based on differential technology is, and Canny operator, such as the Laplacian operator, Sobel operator, edge detection and they can only achieve a pixel-precision positioning accuracy, is very sensitive to noise and differential operators often have a f
