Distortion-less Data Hiding and Extraction using Watermarking by Wavelet Transform
This distortionless image data hiding algorithm based on wavelet transform that can invert the stego-image into the original image without any distortion after the hidden data are extracted. This algorithm hides data into one (or more) middle bit-plane(s) of the wavelet transform coefficients in the middle and high frequency subbands. It can embed much more data compared with the existing distiortionless data hiding techniques and satisfy the imperceptibility requirement. The image histogram modification is used to prevent grayscales from possible overflowing. Experimental results h
