边缘提取在模式识别、机器视觉、图像分析及图像编码等领域都有着重要的研究价值。人脸检测技术是一种人脸识别技术的前提。文章针对人脸检测中人脸定位提出了人脸轮廓信息提取技术，确定人脸检测的主要区域。首先介绍了几种边缘检测算子，然后提出了动态阈值方法来改进图像阈值，提高了边缘检测精度。
邊緣提取在模式識彆、機器視覺、圖像分析及圖像編碼等領域都有著重要的研究價值。人臉檢測技術是一種人臉識彆技術的前提。文章針對人臉檢測中人臉定位提齣瞭人臉輪廓信息提取技術，確定人臉檢測的主要區域。首先介紹瞭幾種邊緣檢測算子，然後提齣瞭動態閾值方法來改進圖像閾值，提高瞭邊緣檢測精度。

Edge extraction has important research value in the fields of pattern recognition, machine vision, image analysis and image coding. Face detection technology is prerequisite of face recognition technology. In view of person face localization in person face detection, the dissertation proposes an extraction technology of face outline information to identify the main regional of face. This article first introduced several edge detection operators, and then proposed the method of dynamic threshold value to improves the image threshold value, which increased the edge detection accuracy.
