This study deals with methods focused on estimating blood velocity. The estimation of the linear trend function of a non-stationary signal based on the adaptive recursive estimation of the mean value function is used for the determination of the time delay of two indicator dilution curves. The filter property of this trend operator depends on the choice of a constant parameter c, the so-called adaptation factor. The functional connection between the filter property and the adaptation factor is considered in such a way that an objective calculation of arterial blood velocity in retinal vessels is possible.
本研究涉及专注于估计血流速度的方法。基于均值函数的自适应递归估计来估计非平稳信号的线性趋势函数，用于确定两条指示剂稀释曲线的时间延迟。这种趋势算子的滤波特性取决于一个常数参数c（即所谓的自适应因子）的选择。对滤波特性与自适应因子之间的函数关系进行了考量，以便能够客观地计算视网膜血管中的动脉血流速度。
