<p>In order to progressively transmit a digital image (IM), a method for coding the image comprises the division (E1,21) of the image into vectors (Vm,n), the selection (E2,22) of a code vector (VCd) associated with an index (Ad) for each of the image vectors, and the replacement (E2) of the image vectors by the indices associated with the selected code vectors, in order to produce a plane of indices (PI) representing the image. The method comprises the steps of sub-sampling (E3,24) the plane of indices (PI) into sub-planes of indices (SPI1 to SPIF) respectively comprising indices selected from the plane of indices, and ordering (E4,25) the sub-planes of indices according to a predetermined order before transmitting them. <IMAGE></p> |
