给出了一种提取主运动能量的自适应滤波算法，通过剔除背景和噪声的频率成分，有效地检测出运动目标。

Then an adaptive filter is designed to extract the motion energy and pick out the frequency components of static background and noises, and the moving targets can be detected effectively.

从移动机器人运动能量损耗的角度对移动机器人全局环境未知时的路径规划问题进行了探索，提出了一种新的基于局部最小能量的路径规划算法。

The robot path planning under unknown plane environments is reviewed from an energy-consuming viewpoint, and a novel path planning algorithm based on the local minimum energy is proposed.
