A Research on the Robust Digital Watermark of Color Radar Images

摘要：

Color images play a more and more important role in actual life, and the wavelet transformation technique is effective in image analyzing and processing. Thus the color-image watermark algorithm based on discrete wavelet transformation(DWT) begins to draw an increasing attention. This paper puts forward a robust watermarking algorithm based on wavelet transformation, which takes the masking of Human Visual System (HVS) in color images into full consideration, and color images are transferred from RGB space to YCbCr space. By means of the fine independence of YCbCr space, the contents and information of host images in every independent color channel can be fully excavated and then embedded in color images after being Arnold scrambled. The experimental results show that watermark embedded by this algorithm is of better robustness and invisibility.
