基于光流计算方法统一框架理论,研究了一种利用高斯多维滤波器的渐进性和时空性提高光流估计性能的有效方法。在保持现有光流计算方法的前提下,通过调节时间维和空间维的方差参数,改变时空预滤波和光滑效果,突出时间混叠和光流主信息,从而提高重构视频序列的信噪比。试验中以标准的Flower Garden和Football序列的前50帧作为参考图像序列,以LK算法为参考光流算法。结果显示,滤波窗口为5×5时的最佳时间方差参数为0.4,最佳空间方差参数为[1.6,2.0];加入高斯多维预滤波前后利用光流场重构图像的平均峰值信噪比PSNR提高2.572dB,提高幅度为13.6%。

Knowledge representation is the core of artificial intelligence research. Knowledge representation methods include predicate logic, semantic network, computer programming language, database, mathematical model, graphics language, natural language, etc. To establish the intrinsic link between various knowledge representation methods, a unified knowledge representation model is necessary. According to ontology, system theory, and control theory, a standard model of knowledge representation that reflects the change of the objective world is proposed. The model is composed of input, processing, and output. This knowledge representation method is not a contradiction to the traditional knowledge representation method. It can express knowledge in terms of multivariate and multidimensional. It can also express process knowledge, and at the same time, it has a strong ability to solve problems. In addition, the standard model of knowledge representation provides a way to solve problems of non-precision and inconsistent knowledge.
