| 摘 要： | 常用的空域定向滤波模板方法具有较好的方向针对性，但是对于某些研究方向，如提取遥感图象线性特征等，常用的定向滤波模板不太适合，原因是它所提供的多个方向中，有重复多余的方向，因而模板方向就少得不足以全面反映被处理遥感图象的特点，不利于图象中线性特征的提取及模式识别。文章在常用的空域定向滤波模板基础上，对构造新的多方向和多尺寸的滤波模板，进行了有效的研究及详细的阐述。

| Abstract: | The commonly used spacial directional filtering template is of great aim at direction,but as for some research work such as extracting the lineaments of remotely sensed image,the commonly used spacial directional filtering template is not suitable.Because many directions of it are of repetition,template directions are too few to represent fully the characteristics of the remotely sensed image to be processed,and it is unfavourable for image lineaments extraction and pattern recognition. On the basis of the commonly used spacial directional filtering template,we make an effective study and exaustive exposition of constructing multi direction and multi size filtering template in this paper. |
