摘要
探讨噪声在图像处理过程中的影响 ,使用visualbasic开发平台对多种边缘抽取算法进行处理 ,观察有噪声和无噪声的情况下的不同。在对比几种方法后 ,得出运算窗口越大对噪声越不敏感 。
In this paper, the influence of noise in image processing is discussed and several edge detection's algorithms is presented with Visual BASIC. The conclusions are that the more large the operation window is and the lower the rank is ,the more insensitive the detection is to noise.
