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.
Claims29
One or more processors comprising:
- circuitry to:
- identify at least a first region of an image and a second region of the image that overlap at an overlapping portion;
- for a pixel within the overlapping portion that lacks a corresponding optical flow vector, use one or more optical flow vectors of the first region to calculate motion to convert the pixel to a valid pixel;
- and
- for each pixel within the second region that lacks a corresponding optical flow vector, iteratively use one or more valid pixels within the overlapping portion comprising the converted pixel to calculate motion to convert each pixel;
- and
- update a flow map to generate a second flow map based at least in part on the conversion of each pixel within the second region that lacks a corresponding optical flow vector.
