| 摘 要： | 提出一种基于可分离Gabor滤波的纹理分析新方法,该方法把传统的Gabor滤波器分解成为两个相互正交的低通和带通滤波器,以降低滤波运算量;并指出在正交分解条件不满足的情况下,通过旋转样本图像,解决Gabor滤波器在任意角度的正交分解问题.实验表明,新方法与传统方法相比,效率提高30%以上,并且准确率更高.

| Abstract: | A new method for texture analysis based on separable Gabor filters is put forward,that separates a traditional Gabor filter into a low-pass and a band-pass filters which are in quadrature,in order to reduces the amount of calculation in filtering;A scheme to resolve the problem of decomposing Gabor filters with arbitrary angles in quadrature is also mentioned.When condition of decomposing in quadrature is not contented,an image can be rotated to be filtered.Experiments indicate that:comparing with traditional methods,the new method has higher accuracy and increases the efficiency more than 30 percents. |
