摘　　要：为了改善影像质量,加强图像判读和识别效果,利用线性空间滤波器在MATLAB的平台上对遥感图像进行图像增强。本文采用了两种拉普拉斯滤波器进行图像增强及其比较。实验表明:线性空间滤波是一种有效的影像增强方法.所得结果能很好地改善遥感图像的影像质量及视觉效果,采用考虑对角元素的空间滤波器要比只考虑上下左右元素的空间滤波器效果更加清晰。并且其算法简单易操作。该成果体现了线性空间滤波器在遥感图形处理技术中的实用价值及意义。To improve the image quality and strengthen the image interpretation and identification of the remote sensing images,using linear spatial filter images enhanced in MATLAB.Through the use of two experimental Laplace filter images are enhance and compared.Experiments show that linear spatial filtering is an effective image enhancement methods,the results can be very good to improve the image quality and the visual effects of remote sensing images,The spatial filter which consider the diagonal elements is better than that which does not consider the diagonal elements.And the algorithm is simple which operates easily.The result of the experiments embodies the linear spatial filter's practical value and significance in remote sensing image processing technology.
