Abstract

A method for transferring a picture image file from a transfer end to a receive end, comprising the following steps of: providing a first set of blocks at the transfer end; dividing the picture image file into a plurality of blocks at the transfer end; comparing the plurality of blocks with a first set of blocks to generate a correlation parameter for each block; determining whether the correlation parameter for each block is not less than a correlation threshold, and removing each of the blocks with the correlation parameter not less than the correlation threshold; generating a reconstruction information which records the linkage relationship between each of the plurality of blocks; transferring the plurality of blocks those are not removed and the reconstruction information to the receive end; and reconstructing the plurality of blocks into the picture image file based on the reconstruction information and a second set of blocks.
