Abstract: Apparatuses, systems, and techniques to calculate motion of one or more pixel in a region in an image. In at least one embodiment, motion is calculated based on motion of one or more pixels in a different region of said image that overlaps said region in which one or more algorithms are expressed in CUDA code, for example, for efficient execution on a GPU.

Abstract: Systems and methods estimate optical flow vectors for occluded pixels between frames of a video sequence. Regions of occluded pixels may be identified and a cause of their occlusion may be determined. Different estimation techniques may be applied based, at least in part, on the cause of occlusion to provide a lightweight, less resource intensive estimation of optical flow data. Optical flow vectors for pixels that are occluded due to movement out of a frame may be estimated using a first technique while optical flow vectors for pixels that are occluded due to foreground movement may be estimated using a second technique.
