| 摘 要： | 针对图片易受到噪声的干扰很难检测到真正的边缘,提出了一种新的边缘检测算法,该算法首先对含有噪声的图片采用二维小波分析和图像的中值滤波进行图像平滑预处理,然后采用遗传算法改进的sobel边缘检测算法对图像进行边缘检测.再对预处理的图片进行Canny算子检测,得到清晰的连续的边缘.把sobel边缘检测算法和Canny边缘检...

An Improved Edge Detection Algorithm |

| Abstract: | Images are vulnerable to noise is difficult to detect the true edge,A new edge detection algorithm is proposed.The algorithm first carries out pretreatment which smoothed by the two-dimensional wavelet analysis and mid-value filter wavelet for image with noise.Then the genetic algorithm improved sobel edge detection algorithm on the image edge detection.then the uses Canny operator edge detection for image preprocessing to obtain a clear and continuous edge.Wavelet analysis of method fuses two images which obtained by the sobel edge detection algorithm and Canny edge detection algorithm.Finally used MATLAB has carried on the simulation.The simulation result indicated that The algorithm has a strong image noise suppression,the extracted edge location accuracy,continuity,clarity is a very effective edge detection methods. |
