| 摘 要： | 使用二种方法进行边缘检测。第一种方法为传统方法;第二种方法为新方法。第一种方法:先用Sobel算子做边缘检测,再用Ostu方法二值化边缘,最后用多像素边缘细化算法进行细化;第二种方法:先用Sobel算子做边缘检测,再用Sobel算子对边缘进行细化,最后用自适应的动态阈值计算方法进行二值化。结果表明:第二种方法在结果和时间上都要优于第一种方法。

| Abstract: | He use two methods to detect edge. The first method is a traditional method; the second method is a new method. Method one: First do Sobel edge detection operator, Second use Ostu to binary edge, Finally, refine edge by multi-pixel to the edge of the edge thinning algorithm; Method two: First do Sobel edge detection operator, Second refine edge by Sobel algorithm, Finally, use the dynamics of adaptive threshold to binary edge. |
