Abstract

The invention relates to a method and device for digital image compression, comprising the application (6) of a transformation in order to obtain a representation of the image comprising a set of coefficient blocks, each coefficient block comprising a plurality of coefficients, termed frequency coefficients, followed by the application of quantification and coding (10) of the coefficient blocks, in order to obtain a set of digital data representative of the compressed digital image. The method according to the invention comprises, after obtaining the coefficient blocks, for at least one processed block selected from among the coefficient blocks, calculation (8) of a first value representative of said block processed using the frequency coefficients of said process block, and the obtaining (8) of a second value representative of said process block, calculated as a function of a model of noise associated with said processed block. The quantification and coding (10) of the processed block takes account of said first and second values associated with the processed block.
