Description: color image tamper detection and self-recovery algorithm Zhao Chunhui, Sun Jianjun, Zhu Haifeng (Harbin Engineering University, Information and Communication Engineering Institute, Harbin, Heilongjiang 150001) Abstract : digital watermark image authentication is one of the effective means. Using wavelet transform A simple calculation of the color image watermarking algorithm, an image of the main elements embedded in the image itself, and use of quantitative methods mean the luminance signal embedded watermark, achieve tamper detection and localization tampering with the region; use of surplus space embedded color luminance signals and chrominance signals, for the restoration of tampering with the image content. The algorithm can generate a higher signal-to-noise ratio of the peak value, h
