what is optical flow
Definitions of optic flow. Optic flow is defined as the change of structured light in the image, e.g. on the retina or the cameraâs sensor, due to a relative motion between the eyeball or camera and the scene. Further definitions from the literature highlight different properties of optic flow.igure 1: shows the production and detection of optic flow. a) Optic flow is generated on the retina by changes in the patterns of light. The example shows the shift of two visual features (star and hexagon) on a plane and their angular displacements on the surface of the eyeball.
