Photographic Map Information Hiding Algorithm Based on Wave Band Fusion

The photographic map is one important kind of maps with the ground digital photographic map. There are many researchers do the research on digital vector map but very few about photographic map. And these photographic map watermark algorithms are based on improved image features digital watermark algorithms, which have some faults influencing the watermark information. To resolve this problem a new Photographic map information hiding algorithm based on wave band fusion is proposed. In this algorithm multi-wave band data fusion technique and pixel value interpolation are employed. Experimental results demonstrate that the proposed algorithm has good preference.
