METHOD, DEVICE, AND COMPUTER PROGRAM PRODUCT FOR COMPRESSING AN INPUT DATA SET

摘要

The invention relates to a method, to a device (100), and to a computer program product for compressing an input data set. The device (100) comprises: a tolerance range determination unit (20) for determining a tolerance range; an encoder (30) for generating encoded lossy values by lossy encoding of the input values; a decoding unit (40) for generating decoded lossy values associated with the input values, in particular by decoding of the encoded lossy values; a subtraction unit (50) for subtracting each decoded lossy value from the respective associated input value and generating differential values; a comparison unit (70) for comparing each differential value with the respective associated determined tolerance range; a correction value generation unit (60) for generating encoded correction values based on the differential values; and an output data set supply unit (80) for supplying an output data set (90) as a function of a comparison of the differential values with the tolerance ranges and on the basis of the encoded lossy values and/or the encoded correction values.
