A method for accessing a region of an encoded image comprising a plurality of segments that are encoded and put in order of encoding. The method includes the following steps applied to encoded segments and by going through the segments in the opposite direction to their order: comparing the position of the current encoded segment with the region of the image to be accessed, and according to the result of the comparison, deciding as to the decoding of the current encoded segment.
