摘要: 经验模式分解(EMD)是最近提出的新的图像多尺度分析方法。通过对纹理图像进行二维经验模式分解来提取合适的纹理特征,再采用FCM聚类算法进行分割,实验表明,使用径向基函数在筛分过程中进行插值的效果较优。

Abstract: A method in which texture image is decomposed into several IMFs by BEMD and features are clustered using Fuzzy C-Means is proposed in this paper.Extrema detection and interpolation plays an important role in the sifting process.Radial Basis Functions(RBF) is chose for interpolation.The features of IMFs are then clustered using FCM.The experimental results indicate that RBF is fit for the interpolation procedure of sifting and the method proposed in this paper is stable,reliable and efficient.
