摘要
本文根据分数布朗随机场(FBR)模型理论,运用小波变换法先对图像进行去噪,然后对图像的分形参数H进行估计,进而根据分形参数H的值的奇异性来检测图像的边缘。实验表明,本文的算法能有效地抑制噪声的影响,并能更好地检测出图像的边缘。
In this paper, according to the theory of fractional Brownian random field model, a new algorithm based on fractal to detect the edges of fractal image. Wavelet transformation is applied to remove of the noise and calculate the fractal dimension. The experiment show that the algorithm can effectively avoid the affection of noise and detect the edges better.
