In view of feature of image retrieval, the position parameter of IFS code is replaced with the relative distance and direction parameter.

针对图像检索的特点，将分形码中的位置参数替换为相对距离与方向系数。

The anisotropic diffusion methods based on the direction of the image feature proposed in the paper is efficient and can get anticipate results.

所以，基于图像特征方向建立的各向异性扩散滤波方法更能达到我们预期的效果，该设计方法是有效的。

The fuzzy direction feature combines the fuzzy image division with the fuzzy direction property feature, which describes the stroke direction property of single edge point.

用模糊方向属性特征描述单个边缘点笔画方向属性； 模糊方向特征是图像的模糊划分和边缘点的模糊方向属性特征的结合。
