英语翻译
A neighborhood analysis (convolution filter) was performed on the LDI coverage where each cell received the LDI value represented
by the mean LDI value within a square window (120 m×120 m) surrounding and including the cell (14,400 m2).
那convolution

用一个120 m×120 m的分析窗口对LDI影象做邻域分析,返回的像元值是分析窗口所覆盖的范围内所有像元的平均值.
(注:LDI应该是某种雷达影象图的简称.)
