The goal of this effort is to establish conventions about quantities for lossless and primarily lossy compression algorithms that are useful for users to define and set.
Please register on our mailing list.
Our strategy and timeline for establishing these conventions are as follows:
The following list of quantities contains candidates for the standardisation. They can be classified into: 1) accuracy/precision loss bounding quantities for lossy algorithms; 2) performance related quantities; 3) other quantities
These quantities define the tolerable error on individual values or multidimensional fields of data from a given datatype. The definition is mostly based on the notion of the term error, which is the residual when subtracting the (lossy) compressed value (d) from the true value (v).
