Image Watermarking using PN Coding Operation where Frequency Band
주파수 대역별 형태소 PN부호화 연산을 통한 이미지 워티마킹
Abstract
This paper has been studied a Image watermarking using PN coding operation where frequency band. By using wavelet transformation, This gets high frequency place HH2 where image watermark puts. Also this places that PN code and binary image are operated. And then, this paper has designed image watermarking index process and extract process, watermarked image which are to add noise is able to extract watermark.
