摘要
提出了一种基于数据融合的图像边缘检测算法。此种方法对初始图像分别采用“Rob-erts”算子和“sobel”算子及小波变换三种方法进行边缘提取,再将三种算法结果通过数据融合的手段获得一幅新的边缘图像。实验结果表明,该方案所得到的边缘图像的效果优于单独采用“Sobel”或“Roberts”算子所获得的边缘图像,是一种行之有效的图像边缘提取算法。
In this article a new image edge detection method is presented. According to this method, edge detection is made with the traditional algorithms such as ＂Sobel＂ and ＂Roberts＂ firstly, and then wavelet transform is combined with these algorithms. Simulation result shows that the new method can be used effectively to provide clearer and smoother edges than that conventional methods such as ＂Sobel＂ or ＂Roberts＂ algorithms alone.
