Abstract of the disclosure Images are approximated by invariant densities of stochastic processes, e.g. by so-called fractals. The parameters of those stochastic processes whose invariant densities approximate the images to be compressed in the sense of a quality criterion to an optimal extent give a compressed representation of this image. These optimal stochastic processes are found with the aid of a sto- chastic optimization process, preferably with the aid of a genetic optimization process. The genetic optimization process makes use, in this case, inter alia of mutation, crossover and exchange of genes for the alteration of the genetic information. With the aid of the process, extremely high data compression factors, typically between 1000 and 10000, are attainable. The process is suitable both for the data compression of still images and also for the compression of images derived from moving image sequences.
