Optical flow vs frame sampling

WebSep 10, 2024 · Optical flow, which is what we’re looking at today, uses motion estimation to generate new frames from the source. Essentially, the software interpolates the missing frame by analyzing and comparing pixel data from the surrounding frames, creating what would appear in-between. Three frame interpolation methods.
