Abstract

For measurement of moving objects in stereo vision, IAE filter was introduced and a method of the IAE filter window dynamic resizing (IAE-DW) was proposed. Firstly, the range of window size was constrained according to the relation between the window size and standard deviation estimation error of the IAE. Then the window size was adjusted dynamically based on the variance ratio of standard deviation calculated with the change rate of motion depth. Thus, the estimation accuracy of IAE to noise statistics can be improved. The experimental results demonstrate that the proposed algorithm can provide better filtering ability.
