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, a simplified method of calculating an approximation of vx by substituting vy=0 into the first equation of Equation 4, and an approximation of vy by substituting the calculated value of vx into the second equation may be used. In this case, vx and vy are expressed as shown in Equation 7.
