Optical flow image

WebThe first step in motion perception is for the visual system to estimate optical flow from the changing pattern of light in the retinal image. Then, the 3D motions of observer and objects can be inferred from the optical flow. The optic flow then provides information about the observer's heading and the relative distance to each surface in the ... WebOct 2, 2024 · Your two images are quite different. Optical flow works best when the objects move around 1px per frame. The results may be easier to interpret if you use images that are more alike. – Stephen Meschke Oct 1, 2024 at 21:41 @StefanvanderWalt Thank you, I already saw that it was in development.
