Histogram Modification and Wavelet Transform for High Performance Watermarking

Figure 5

The proposed data embedding principle: (a) the original host image (b) decomposes into sixteen subbands, (c) generates the random sequence of the subbands, (d) selects the random starting location and direction of each subbands (e) An example of embedding watermark into pixel sequence; (f) rearranged watermarked subbands; (g) the watermarked image.
