Validated from ground truth data, the result shows that MODIS data has great potential in fog detection.

结果表明，MODIS数据在雾检测方面具有很大的潜力。

The method of generating the image sequence and ground truth based on ray - tracking in the optical flow;

采用基于特征的光流法，由单面冠状动脉造影图像序列估计二维血管的运动。

When the ground truth is given, performance evaluation can be readily carried out by comparing detected edges with the ground truth edges.

当有背景时，性能评估可以通过将检测到的边界与真实背景作比较得出。

Those who manage information resources for research and teaching would take it as ground truth that research is a global and distributed phenomenon.

为了研究及教学而管理资讯资源的那些人，将研究是一种全世界性并且被分布的现象当作基础的事实。
