Improved Based DCT Correlation Watermarking
Journal Title: International Research Journal of Applied and Basic Sciences - Year 2014, Vol 8, Issue 9
Abstract
In this paper, an improved based DCT correlation watermarking has been proposed. In the proposed scheme the watermark is scrambled and reshaped to a sequence; then two separate PN sequences are used to encode “1” and “0”, separately. The secured watermark is embedded into DCT blocks coefficients of the intended channel from the host image which has been converted to CIELab color spaces. Experimental results, compared with the related existing methods, show that the proposed scheme improves the similar algorithms.
