Data Hiding Techniques Based on Wavelet-like Transform and Complex Wavelet Transforms

In this paper we compare data hiding techniques based on wavelet-like transform, viz., Slantlet transform, DD DT DWT and Complex Wavelet transforms, viz., DT CWT using wavelet based fusion method and thresholding method. The experimental results are compared with the existing method based on DWT. We observe that the proposed algorithms based on SLT and DT-CWT outperform the DWT in terms of visual quality and embedding capacity.
