摘要
本文从空间域和频率域对边缘增强的方法进行了研究。在空间域，介绍了一种新的边缘增强方法，该方法克服了目前常规方法的缺点，能有效地改善影像质量。试验证明，经处理后的图像边界清楚，影像清晰，极有利于目视判读。在频率域，进行了高通滤波试验，利用高频伽强技术也获得了良好的结果。根据试验，确定了遥感图像的高频加强技术的参数。

In this paper the edge enhancement methods are studied in both of spatial and fre-
quency domain. A new edge enhancement method in the spatial domain is introduced.
This method overcomes shortcomings which often exist in the normal edge enhancement
and is efficacious to improve the image quality. The experiments demonstrated that the
features and edges of image are very clear after processing. The method is very useful
for visual interpretation.
High pass filtering in the frequency domain is also tested. The good results are al-
so obtained using high frequency emphasis technique. Based on the experiments the pa-
rameters of high frequency emphasis have been determined specially for remotely sensed
image.
