Paper Abstract

Advances in 3D scanning have enabled the real-time capture of high-resolution 3D video. With these advances comes the challenge of streaming and storing this 3D video in a manner that can be quickly and effectively used. To do this, different approaches have been taken, a popular one being image based encoding, which projects from 3D into 2D, uses 2D compression techniques, and then decodes from 2D back to 3D. One such technique that does this is the Holovideo technique, which has been shown to yield great compression ratios. However, the technique was originally designed for the RGB color space and until recently could not be used with codecs that use the YUV color space such as the H.264 codec. This paper addresses this issue, generalizing Holovideo to the YUV color space, allowing it to leverage the H.264 codec. Compression ratios of over 352 : 1 have been achieved when comparing it to the OBJ file format, with mean squared error as low as .204% making it a viable solution for 3D video compression.
