摘要
在分析高斯Laplace算子边缘检测原理的基础上,通过设置合理的模板参数,提出了一种改进的高斯Laplace模板,该模板设置的权值具有各向同性、中心点值设置为整数、不同类型方向上设置的权重不等而相同类型方向上设置等权重、并且整个模板无零值点等特点。通过VC++编程使用不同的模板对同一幅图像进行实验,实验结果表明改进的模板能较准确地检测出图像边缘,检测效果优于其他模板。
Based on the analysis of Gauss_Laplace operator edge detection principle, this article advances a upswing Gauss_Laplace templet from setting reasonable templet parameter. The value is same character in all orientation, central value is integer, the value is vary in different type orientation , the value is equality in same type orientation and there is not zero value in the templet, etc. We made a experiment ,which was checking the edge of a picture with different templets by VC＋＋ programme, and the result showed that the upswing one could detect it more truly .And its effect is better than others.
