Abstract
Methods and apparatus for compressing and decompressing MPI videos. According to an example embodiment, a method of compressing an MPI video includes splitting the MPI video into first and second frame sequences including texture and alpha frames of multiplane images, respectively. The method further includes applying sets of preprocessing operations to convert the first frame sequence into a third frame sequence and to convert the second frame sequence into a fourth frame sequence. Example preprocessing operations include, but are not limited to, applying a fill process, thresholding RGB channels based on the corresponding alpha channel, blurring images, computing pixelwise difference values of frames, and computing pixelwise product values of frames. The method also includes applying video compression to the second frame sequence and to the fourth frame sequence.
