人体数字图像 边缘检测 算子 卷积 body digital image edge detection operator convolution

研究数字图像边缘检测的原理以及三大类基于算子的边缘检测算法，并将其应用到二维非接触式测量系统的图像边缘提取过程。通过对各算子的实际应用效果分析，Sobel与Smoothed边缘算子的图像增强效果较好，可有效排除噪声干扰，且轮廓线清晰，有利于轮廓跟踪、修补，从而使系统获取到连续清晰的人体边缘曲线。

This paper discussed the principle of edge detection for digital image and the algorithm based on the edge detective operators. The detective methods have been used in 2D untouched body measurement system for edge detection of digital body images. The result of experiments shows that Sobel anti Smoothed operators have good effects on image enhancement, suppressing the noise and providing clear-cut profile lines. They can be used effectively for body contour detection.
