In our case , there is sufficient overlap among the libraries to permit comparison in terms of speed based on three relatively simple yet revealing tasks , which are displayed and discussed in the following three examples
在我们这里，三个库有足够的重复部分，这使我们能用三个比较简单但能说明问题的任务来比较它们的速度，我们将在下面三个示例中显示和讨论这些任务。
We use the correlation of data between the neighbor scan lines to get the overlay pixel number , and then remove the overlay data . the bilinear interpolation method is applied to assign the pixels with the overlap data . the result shows that the data overlay phenomenon is removed , image quality is improved , and pixel value has been enhanced
此外，对于modis遥感影像中存在的边缘区域数据重叠问题，则利用数据间的相关性计算条带间各列像元的重叠数量，然后删除重复部分，并经灰度重采样后得到结果数据，实验表明影像数据的重叠现象明显消除，从而改善了影像的质量，增强了数据的使用价值。
