Gabor-ring is often used in texture feature extraction, but it is based on the assumption that texture is narrowband signal and can not applied to most actual textured images that have more than one center frequency in power spectrum. To overcome the limitation of existing method, an improved method is proposed. According to this method, Gabor filters are constructed in accordance with the spectrum feature vector of texture, and a relaxation parameter is used to determine the effect of difference filters so as to integrate the frequencies and phases into the process of extraction.
Gabor环(即在频率域成环形分布的Gabor滤波器组)常被用于提取图像纹理特征,但它是以"纹理是窄带信号"为基础的,实际的纹理图像并不能很好地满足"窄带信号"的假设,用一个中心频率来描述一种纹理对能量集中在多个频率点的纹理图像往往不能取得理想的效果,而根据频谱特征值向量构造Gabor环的改进方法,通过松弛因子的加入改变不同滤波器的作用强度,综合考虑了多频率多相位对纹理特征提取的影响。
