Abstract: The images change-detection is the most important and basic technique in the remote science.After a serious of research based on the existing images,the authors have surveyed new effectual change detection method based on edge-enhance.First choose the proper convolution operator to do the crisp enhancement,then use the Sobel operator to do the edge enhancement.The test results show the validity of the method.

摘要: 遥感图像变化检测技术是遥感技术中最广泛最基本的应用之一。为此作者经过大量对已有图像的实验,提出一种基于边缘增强的遥感图像变化检测技术,通过选择适当的卷积算子对图像进行锐化增强与使用Sobel算子对图像进行边缘增强相结合,总结出了快速有效变化检测处理方法。
