- 将原图像看做是自相关及其功率谱是各向同性的一阶马尔可夫过程,采用基于方向微分的运动模糊方向鉴别方法，对运动模糊图像进行方向性的高通滤波(方向微分),当滤波方向为运动模糊方向时 ,由于此方向模糊图像对应的高频成分最少,高通滤波(方向微分)使模糊图像能量损失最大,得到的微分图像灰度值（双线性插值）之和必然最小.所以方向微分得到的图像灰度值之和中的最小值对应的方向即为运动模糊的方向-The original image as is the autocorrelation and power spect

MPPT
- 光伏电池阵列输出功率受光照强度和温度变化的影响，因此最大功率点跟踪（MPPT）技术广泛应用于光伏系统中。在所有最大功率点(MPP)控制策略中，扰动观察（P&O）MPPT算法因易实现被广泛应用，然而它的缺点是在稳定工作状态下工作点通过MPP 时会导致能量振荡损耗，并且在光照强度或温度发生突变时表现较差的动态响应。在本文中，提出一种改进型变步长扰动观察MPPT 算法，此方法依据工作点动态调整步长变化，与传统固定步长方法比较，本文提出的方法能有效地提高MPPT 速度和转换效率，通过仿真和实验结果分析，
