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. Index Terms—Pixel Histogram Shifting (PHS), Dynamic Prediction Error Histogram Shifting (DPEHS), Image Quality Index (IQ), Pearson Correlation Coefficient (PCC), Signal to Noise Ratio (SNR).
