所做工作主要有两方面：一是矢量量化编码中的格型矢量量化，另一个是梅花型方向滤波器的提升实现。
The work can be mainly divided into two aspects: lattice vector quantization in vector quantization coding for images and the lifting realization of the quincunx directional filter banks.
通过计算系统可观测度和采用无迹卡尔曼滤波(ukf)对目标相对运动状态进行估计，研究了观测矢量方向和数量与相对导航精度的关系。
System observability matrix was derived, and the degree of observability was calculated. Relative motion states of non-cooperative space target were estimated through unscented Kalman filter (UKF).
