where OG is the output video with heterogeneous spatial quality corresponding to quality distribution q(⋅), LN(i) is the upscaled Laplace pyramid level i, B is the bitrate budget, Ø is a mapping function that maps for each pixel in each 360° video frame the quality distribution q(⋅) to the optimal levels of the Laplace pyramid given the bitrate budget B, and (x, y) are coordinates of a pixel in the 360° video frame.
