Implementation issues and specific compression algorithms are not addressed. Welcome to the PNG Home Site, maintained by Greg Roelofs. My particular interest is in delivery of music via the Net - with compression which does not affect the sound quality at all. I am primarily interested in compression ratios, not speed of the programs. Unrelated to all other statistcal methods.
Built tree is n-ary one.
However, the requirement for a huge amount of images causes problems both in mass storage and in memory management. In order to make light fields feasible even in low end computers we have to reduce the data size. This project suggests that by using wavelet transform and vector quantization we can achieve pretty high compression ratio with minimun degradation in rendering quality. We present a survey of these methods. Currently this page includes information about VQ with regards to compression.
