Wang cubes for video synthesis and geometry placement

Peter G. Sibley, Philip Montgomery, G. Elisabeta Marai
2004 ACM SIGGRAPH 2004 Posters on - SIGGRAPH '04  
We present an extension of Cohen's Wang Tiles to three dimensions:Wang Cubes. Cubes are filled with video or Poisson distributed points to perform realtime video synthesis or geometry placement.  ...  To fill the cubes with video data, we cut six octahedra from the video stream and stitch them together. Then, the result is trimmed into a cube ( Figure 1b) .  ...  Each original octahedron is associated with a face color. A xy plane in this cube corresponds to a frame of video and the z axis corresponds to time.  ...

New Results in Perceptually Lossless Compression of Hyperspectral Images

Chiman Kwan, Jude Larkin
2019 Journal of Signal and Information Processing  
The key idea is to compare several combinations of PCA and video/image codecs. Three representative HSI data cubes were used in our studies.  ...  Perceptually lossless means that the decompressed HSI data cube has a performance metric near 40 dBs in terms of peak-signal-to-noise ratio (PSNR) or human visual system (HVS) based metrics.  ...  Video Approach As mentioned earlier, the video approach treats the HSI data cube as a video C.

An adaptive three-dimensional DCT compression based on motion analysis

Borko Furht, Ken Gustafson, Hesong Huang, Oge Marques
2003 Proceedings of the 2003 ACM symposium on Applied computing - SAC '03  
The effectiveness of the proposed technique is illustrated by implementing it to a number of video sequences with low, medium, and high motion.  ...  The technique consists of two steps: (a) it analyses the motion within a small (16x16) video cube of eight successive frames, and (b) it selects the size of the cube based on the motion analysis and applies  ...  In the case when the motion analyzer detected "no motion" in a video cube, the 3D-DCT is applied to 16×16×1 cube, which is in fact a 2D-DCT transform applied on the block in the first frame only.  ...
