JPEG – Compression of Digital Hologram

We study effects of storing digital particle holograms by a joint photographic experts group (JPEG) compression. Information content of the holograms is statistically evaluated by measuring the degree of similarity between the compressed and its original holograms. We also extract size and position information of the particle from the compressed hologram. The results show that the hologram could be compressed about 30 times smaller without causing the error of measurement to be bigger than 1%.
