ABSTRACT:
Temporal sequences of predicted measurement data (Y), among which there are predicted movement data (W) relating to temporal sequences of digital images (I), are compared with temporal sequences of measured measurement data (S), among which there are measured movement data (V) relating to the same temporal sequences of digital images (I), by forming differences (D) from measured measurement data (S) and predicted measurement data (Y). These differences (D) are fed to a time-recursive filter (TRF) for estimating temporal sequences of state variables (X). The predicted measurement data (Y), including the predicted movement data (W) are determined from these state variables (X) with the aid of a measurement map (H). These predicted movement data (W) are used to determine (ME) measured movement data (V) relating to the temporal sequences of digital images (I). The method facilitates the determination of spatial structures and the analysis of spatial object movements, including intrinsic movement. Moving objects can be detected and segmented reliably.
