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(More)
Pmose At present there is no method known, which allows to measure retinal vessel diameter with sufficiently minimal error, We present a system for the automatic measurement of the diameter of human retinal branch vessels. The system allows to perform on-line measurements directly at the human fundus. Methods A measuring ophthalmoscope based on the Zeiss(More)
