摘要:

提出了一种基于逆共振滤波(IRF)的纹理模式识别方法。纹理图像信号波动本征谐波分解(EHD)的一组主谐振谐波用于IRF设计。结果表明,EHD对纹理图像线性位移具有不变性。纹理的识别是通过将纹理信号转换成非结构化的纹理信号来实现的,非结构化的纹理信号可以利用简单的统计参数进行纹理模式识别。异物上信号点的异常变化。考虑到纹理信号突变的存在,提出了两种二维EHD参数估计方法。第一种方法是基于对信号相位跳变不敏感的线性对称模型。特征多项式对称的条件提供了模型的平稳性和周期性。第二种方法是基于二维相关矩阵的奇异值分解(SVD)的主向量空间的矩阵束投影的特征值问题。提出了两种纹理图像异物分类检索方法。

英文摘要:

An approach to textures pattern recognition based on inverse resonance filtration (IRF) is considered. A set of principal resonance harmonics of textured image signal fluctuations eigen harmonic decomposition (EHD) is used for the IRF design. It was shown that EHD is invariant to textured image linear shift. The recognition of texture is made by transfer of its signal into unstructured signal which simple statistical parameters can be used for texture pattern recognition. Anomalous variations of this signal point on foreign objects. Two methods of 2D EHD parameters estimation are considered with the account of texture signal breaks presence. The first method is based on the linear symmetry model that is not sensitive to signal phase jumps. The condition of characteristic polynomial symmetry provides the model stationarity and periodicity. Second method is based on the eigenvalues problem of matrices pencil projection into principal vectors space of singular values decomposition (SVD) of 2D correlation matrix. Two methods of classification of retrieval from textured image foreign objects are offered.
