摘要: Generally, High Boost filter is used to emphasize high frequency components representing the image details without eliminating low basic form of signal. The dissimilarity between watermark and unwatermarked parts are increased by this filter. Thus, could be recovered significantly better recovery algorithm. In paper, a comparison taken place effects different places preforming on reliability methods in spatial domain watermarking. This convolved two extraction algorithm; before running calculate correlation middle extraction. paper concentrate conclude which these more proper convolve A classic based method as representative Several experiment done show one for proposed
