The probabilistic data association algorithm is applied in the spatial domain multi resolution frame and target tracking is implemented at the coarseresolution level.
这个算法在空间多分辨率框架下应用概率数据互联算法，在粗分辨率上实现模糊目标跟踪。

In digital imaging, graininess may occur as a result of printing an image, the pixel resolution of which is too coarse, or as a result of using a printer with poor dot resolution.
数码成像时，颗粒状可能会在图片打印时像素分辨率过于粗糙或使用点分辨率过低的打印机时出现。

Owing to the decametric wavelength, the angular resolution of High Frequency Surface Wave OTH Radar (HF SWOTHR) is usually coarse especially when dimensions of antenna array are restricted.
