Recently, non-regular three-quarter sampling has shown to deliver an increased image quality of image sensors by using differently oriented L-shaped pixels compared to the same number of square pixels.

However, the approach does not consider the large field of view of fisheye lenses that requires the consideration of different motion planes in 3D space.

Based on the known projection format of the video, MPA allows to perform inter prediction on different motion planes in 3D space instead of having to work on the - in theory arbitrarily mapped - 2D image representation directly.

Next, we investigate the reconstruction quality using tetromino pixels for the first time in literature.
