A method for reallocating the choice of a processing for sub-sampling upon the criterion of a data transfer rate - reduction of a sequence of auxiliary data, for the reconstruction of a sub-sampled electronic image.

摘要

The purpose of the invention is to have a higher performance of the reduction of flow rate, and a better accuracy in the configuration of a source image hd. / p & & p & the method according to the invention is intended to be applied to a system multiprocessing, in which it determines 41, within the image or picture blocks, the elements of images which are capable of accepting equally well at least two separate 5-day treatments under - sampling; and it selects 43 to associate with each of said elements of images to treatments are not critical, one of the treatments are not critical for an optimum reduction in flow rate of assistance data. / p & & p & a preferred application is the image compression by the transmission channel hdtv by mac.
