Server-side processing is principal for most of the current Web-based geospatial data processing tools. However, in some cases the client-side geoprocessing may be more convenient and acceptable. Th...
基于方向WPS改进TDI CCD遥感图像清晰度评价函数
自动调焦 小波 功率谱估计 图像清晰度评价函数
2016/8/31
在轨调焦是航天相机获取高质量图像的关键技术之一。针对航天相机在发射、在轨期间由于振动冲击及温度气压等环境参数变化引起的光学系统离焦现象，以及TDI CCD遥感相机成像场景实时变化的特殊特点，对基于功率谱的清晰度评价函数进行了研究。根据小波变换的多分辨率和带通特性，提出了一种对FFT功率谱的改进——小波功率谱（WPS）估计。针对像移亦会导致TDI CCD图像模糊的问题，提出了方向WPS估计算法。参照...
