对Marr边缘检测算法中LOG算子性能进行了分析和评估,并研究了LOG模板的构造及二值化处理图像的过程。根据实际应用中LOG模板的设计要求,导出了构造LOG模板的一般公式。针对传统LOG边缘检测算法并不能使目标与背景较好分离的不足,文中利用待二值化像素与其4连通区域像素进行比较对算法中二值化方法进行了改进。经实验验证,此改进获得了较好的边缘检测图。实验结果表明,该方法能够满足实际应用的要求,较好地区分目标与背景,同时还保持目标区域的连通性。
對Marr邊緣檢測算法中LOG算子性能進行瞭分析和評估,併研究瞭LOG模闆的構造及二值化處理圖像的過程。根據實際應用中LOG模闆的設計要求,導齣瞭構造LOG模闆的一般公式。針對傳統LOG邊緣檢測算法併不能使目標與揹景較好分離的不足,文中利用待二值化像素與其4連通區域像素進行比較對算法中二值化方法進行瞭改進。經實驗驗證,此改進穫得瞭較好的邊緣檢測圖。實驗結果錶明,該方法能夠滿足實際應用的要求,較好地區分目標與揹景,同時還保持目標區域的連通性。

The performance of the LOG operator in edge detection by using Marr algorithm is analyzed and evaluated,the construction of the LOG template and the process of binarization processing image is discussed. According to the designing requirements,deduced the general formula of constructing LOG template. Aiming at the traditional LOG edge detection does not make the better separation of target and background,improved the method of binarization by using awaiting binarized pixel compared with its 4-connected regions pixels. The experiments prove that this improved gets better edge detection. Experiment results show that this method can meet the application re-quirements,distinguish the object from the background perfectly,and can keep connection of detection area well.
