20.4 简单纹理变换

纹理变换用于增强特定的图像结构。变换的效果取决于所使用的滤波器（HALCON 提供多种不同的纹理滤波器）。

  read_image(&Image,"File_xyz");
  Filter = "ee";
  texture_laws(Image,&TT,Filter,2,5);
  mean_image(TT,&Lp,31,31);
  threshold(Lp,&Seg,30.0,255.0);

• mean_image 必须使用较大的掩模来调用，才能达到足够的泛化效果。

• It is also possible to calculate several different texture transformations and to combine them later, using add_image, mult_image or a similar operator.
