| 摘 要： | 提出了一种基于EMD分解的四元数域无监督纹理分割方法。首先采用二维可分离EMD分解提高各图像成份的四元数Fourier频域特征的分离度，再使用四元数Gabor滤波器组进行解析特征提取，最后利用新的模糊c均值聚类评价函数实现无监督的纹理分割。实验结果验证了该方法的有效性。

| Abstract: | This paper presents an unsupervised texture segmentation algorithm in quaternion-domain based on empirical mode decomposition. This method uses 2-D separable EMD to enhance the separability of features in frequency domain, then a quaternionic Gabor filter bank is designed to extract analytic features and a novel validity function of fuzzy c-means clustering is introduced to realize texture segmentation. Experimental results indicate the effectiveness of the method. |
