Introducing affine transformation parameters in future extraction, makes the new features can take a good deal of the situation of target rotation.

在提取特征的时侯，引入仿射坐标参数，使得新特征能很好的应对目标旋转的情况。

Experimental results show that the algorithm has an invariant property with respect to the shift, scale and rotation of the moving target in the continuing detection of moving targets.

通过实验结果可以看出，该算法不仅能适应复杂多样的背景环境，而且对运动目标的连续检测能力具有位移不变、伸缩不变和旋转不变的特性。

If the target slab is deemed suitable, a number of test holes are likely to be drilled - using the rotation as well the percussive action - before a powdered sample is picked up and delivered to Curiosity's onboard laboratories.
