This package is lsb add this digital watermarking algorithm for an improved method, of which there are three key documents Mylsb.m modify_lsb.m and. Modify_lsb2.m these three documents is the lsb of this algorithm three different degrees of improvement of , one of the more than one change, mainly involving the improvement method is to add a watermark when we used the eight pixels to determine the clinical domain of the value should be inserted, followed by the method is to use a switch to a different color space for watermark insertion. Comparison of the effect of insertion through my_hist.m to display the document.
