Abstract: A method, device, and apparatus for determining optical flow from a plurality of images is described and includes receiving a first image frame from a first plurality of images, where the first plurality of images have a first resolution and a first frame rate. A second image frame may be received from a second plurality of images, where the second plurality of images have a second resolution less than the first resolution and a second frame rate greater than the first frame rate. A first optical flow may be computed from the first image frame to the second image frame. Additionally, the based at least in part on the first optical flow from the first image frame to the second image frame, a third image frame may be output as part of an output stream. The output stream may have a frame rate greater than or equal to the first frame rate, where the third image frame has a resolution greater than or equal to the second resolution.
