Description: Firstly, research on robust image watermarking. A digital watermarking scheme based on wavelet transform was proposed. It realizes the watermarking extract without the original image using 64×64×8 bit gray image as the watermark signal. In order to enhancing the security of the watermark, we employ an encryption technology based on chaos and bit plan. Simulation results show that our scheme have good invisibility and can survive low-quality JPEG compression, median filtering and so on. In addition, the analysis of the extracted watermark can help us to detect and localize tampers. Platform: |

Description: 数字水印处理系统主要由水印嵌入和水印检测两个过程。（1）水印嵌入过程为：数字水印（X）、原图像（I）和密钥/公钥（K）通过数字水印嵌入算法形成嵌入水印后的图像（I*）。 （2）水印检测过程为：数字水印（X）、水印图像（I*）和密钥/公钥（K）通过数字水印检测算法检测出数字水印或有无水印。该程序调试已通过！-Digital watermarking system mainly consists of watermark embedding and watermark detection of the two processes. (1) The watermark embedding process as follows: Digital watermarking (X), the original image (I) and key/public key (K) by digital watermark embedding algorithm to form watermarked image (I*). (2) The watermark detection process is as follows: Digital watermarking (X), the watermark image (I*) and key/public key (K) by digital watermark detection algorithm to detect whether the digital watermark or watermark. The program debugging has passed! Platform: |

Description: A new method of video scene content characteristic detection is proposed. This method
can be applied in conjunction with digital watermarking schemes in order to improve the
transparency. In addition, new methods of video watermarking are also proposed. Three related
original aspects are reported. First, the authors’ previous robust image watermarking methods,
which consider the block texture are extended into video. In the detection process, watermark
extraction with or without the original frame is provided. Secondly, a method is proposed to
improve imperceptibility by reducing the flickering effect. Finally, a method is introduced to detect
video scene characteristics in order to suit the particular embedding scheme. By doing so, the
embedding method can be chosen adaptively in accordance with the video scene. The subjective
tests illustrate an imperceptibility improvement and experiments with various attacks show the
watermarking robustness.
