Histogram Shifting Techniques For Enhancing Psnr, Iq, Pcc And Snr
Reversible water marking technique for enhancing the different parameters of the images like PSNR, IQ, PCC
and SNR. Watermarking technique classify the image using invariant image classification and after that depending upon the
images respective Pixel Histogram Shifting (PHS) and Dynamic Prediction Error Histogram Shifting modulation (DPEHS)
is done. It provides a very good authentification, image classification for different images.
