Hello everyone
i am applying image normalization technique and DCT technique for embedding and extraction watermark image. here i am getting Normalized Correlation with negative sign after extracting watermark image. e.g.
-0.9967
-0.9966
-0.9896
-0.9697
-0.9946
i just want to know that is it right or wrong ? why NC value is coming negative either due to applying DCT or image normalization ? plz clear my doubt.. thanks in advance
