オプティカルフロー検出の精度向上とデバイスへの応用

Optical Flow estimation is useful to describe the velocity information of motion image relative to the observer, and gradient based method is often used. In this method, we must choose a suitable weighting factor determined by the average brightness level and noise in the image, denoted by α^2. In this paper, we proposed to vary α^2 according to the local brightness level and noise in the image, and parallel analog image processors for motion detection circuitry based variable method we designed α^2. Using this method, we can improve the accuracy of motion estimation of any condition.
