Motion compensation method and device using bidirectional optical flow
地域：
Seoul
摘要
Disclosed herein is a method for adaptive bidirectional optical flow estimation for inter-screen prediction compensation during video encoding. The method aims to reduce complexity and/or cost of bidirectional optical flow (BIO) at a pixel level or a subblock level.

As another example, an approximation of vx may be calculated by substituting vy=0 into the first equation of Equation 4, and vy may be calculated as the average of a first approximation of vy obtained by substituting the approximation of vx into the second equation and a second approximation of vy obtained by substituting vx=0 into the second equation. Using this method, vx and vy are obtained as shown in Equation 9.
