Abstract
This article reports the results of comparing the compression of object light data for holograms using various lossy compression methods: JPEG, vector quantization (VQ), JPEG2000, and fractal compression. The efficiencies were JPEG2000 >fractal compression >VQ >JPEG at compression rates from 1% to 20%. In particular, when the PSNR was large, it became clear that the compression efficiency of JPEG2000 was very good.
