| 摘 要： | 中值滤波法是图像处理中一种非线性滤波技术，可对图像中的噪声进行有效的抑制，成为空域平滑的重要手段。针对中值滤波法的不足，提出一种基于准十字窗口的中值滤波方法。给出了抑制噪声、对图像边界最大保留的计算方法和运算步骤。并将其用于某型飞机实际红外图像处理实践，利用空间噪声曲线对该方法进行了验证。实践证明了其方法具有简单有效、易于编程实现、迭代性好、计算速度快的特点。 |

| Abstract: | Median filter is one of the non-linear filter methods,which can get rid of image's noise effectively and has become an important approach for spatial smoothing.The authors presented an improved median filter based on improved crossing,which can get rid of image's noise effectively and preserve more edge of image.It was used for processing the real IR image of a certain airplane,and the spatial noise curves were used for studying the effectiveness of the method.It is proved that the method is simple,effective and easy to realize. |
| Keywords: | image processing improved crossing median filter infrared image noise |
