根据模糊图像的频谱和协方差特性估计模糊图像的模糊度。
According to the frequency spectrum and covariance, the blur strength of the blurred image is evaluated.
利用马尔柯夫估计，推导了GPS整周模糊度估计矢量和导航定位参数估计矢量的表达式，以及相应的协方差矩阵；
The GPS integer ambiguity estimates, the navigation parameter estimates and their variance-covariance matrix are derived by using Markovian estimation.
再以该近似解和协方差矩阵为初值，由无迹卡尔曼滤波(ukf)实时估计双差整周模糊度的精确解。
Then the float ambiguity resolution was passed into an unscented Kalman filter as initial state value. UKF estimated the precise ambiguity resolution in real time with the initial value.
