A extraction method of the directionality of texture image wedge filter based

提出了一种基于楔形滤波器的图像方向信息提取方法。通过设计一个原型楔形滤波器,对该滤波器的系数矩阵进行插值后得到一组方向滤波器。之后,对图像进行滤波,并对各方向滤波器的输出进行判断以提取图像中的方向信息。实验结果表明,该方法简单有效,可用于纹理图像的方向检测。

A method of the directionality extraction method of the texture image is proposed.First,a prototype wedge filter is designed,after the interpolation of the coefficient matrix,a bank of directional filter is obtained.After filtering the image,determine the orientation information of the image through the output of the filters.It＇s shown that,the method is simple and effective for the extraction of the orientation information of texture image.
