Fixed-PSNR Lossy Compression for Scientific Data [PDF]
2018 IEEE International Conference on Cluster Computing (CLUSTER), 2018 Error-controlled lossy compression has been studied for years because of extremely large volumes of data being produced by today's scientific simulations. None of existing lossy compressors, however, allow users to fix the peak signal-to-noise ratio (PSNR) during compression, although PSNR has been considered as one of the most significant indicators ...
