Abstract: The invention relates to the coding and decoding of data, in particular for visual representation. For this, a method (100) is provided for coding an initial data set (110), in which a respective initial data value (P1, P2, P3, P4) is established for a respective plurality of initial data points (112), for generating a compressed data set (114), comprising a primary coding of the initial data set (110) to generate an intermediate data set (116) and a secondary coding of the intermediate data set (116) to generate the compressed data set (114).

Abstract: The invention relates to a method for compressing an input data set, which comprises one or more input values, comprising the following steps: determining, for each input value, a tolerance range; generating encoded lossy values by a lossy encoding of the input values; generating output values associated with the input values, in particular by decoding the encoded lossy values; generating difference values by subtracting each decoded lossy value from the respectively associated input value; comparing each difference value with the respectively associated determined tolerance range; generating encoded correction values associated with the encoded lossy values on the basis of the difference values, wherein the encoded correction values are offset values, which can be added to the associated encoded lossy values; and providing an output data record as a function of a comparison of the difference values with the tolerance ranges and on the basis of the encoded lossy values and/or the encoded correction values.
