DIGITAL IMAGE PROCESSING METHOD FOR LOW-RATE APPLICATIONS

摘要

The present invention relates to a method of processing digital images ( 30 ) comprising data blocks, said method including a step of determining ( 31 ) a homogeneous region containing two adjacent blocks (Bj, Bk) whose continuous components (Lj, Lk) differ by a value lower than a predetermined threshold. It also includes a step of determining ( 32 ) a segment to be corrected (Sjk) which comprises a set of initial data on either side of a border separating the adjacent blocks. The method finally comprises a step of replacing ( 33 ) the set of initial data of the segment to be corrected by a set of corrected data (S'jk) chosen at random from various possible corrected data sets ( 34 ), an average value of a corrected set of data being substantially equal to an average value of the continuous components of the two adjacent blocks.
