The investigations in this thesis focus on several aspects as follows: We investigate the method that how to produce permutation matrix by using chaotic map, and get the method of image permutation based on chaotic map. This method can make original image to unorderly image to protect the true content of image. We investigate gray level mix function, and put forward a gray level mix function based on chaotic map. Because this function has chaotic characteristics, the image dealed with this function has very uniform histogram. Aiming at the contradiction between error robust and security on image encryption, we put forward a kind of gray level mix function including diffusion mechanism.

To increase the security of the watermark, a new binary image encryption algorithm based on TD-ERCS map is presented. The watermark is encrypted by a chaos sequence generated by TD-ERCS map; A novel color image watermarking algorithm is proposed based on discrete chaotic map and 2-dimensions discrete wavelet transform. The watermark is encrypted by the new binary image encryption algorithm, and the encrypted watermark is embed into four sub-bands of the most deep level of blue branch of host image by three-level wavelet transform, and the embedded positions are determined by general cat cha otic map; A novel color-image blind detection watermarking algorithm is proposed based on integer wavelet transform and subsampling. The scrambled watermark is encrypted and embed into the low sub-bands after four sub-images of the Y branch of host image is transformed by two-level wavelet transform, and the embedded positions are determined by Logistic chaotic map, this watermarking scheme can realize blind extraction.

Using the image of comparative literature on the theory and methodology, this paper cards Western image of the ancient Chinese before the Qing Dynasty and analyzes the characteristics of the traditional mode of thinking and collective imagination at the beginning. Then, connecting the above features, it focuses on the image of the United Kingdom in travel notes of the Qing Dynasty and analyzes the role and significance of the travel notes and the officials in the formation of "the image of the United Kingdom" in the Qing Dynasty. That is, travels text is a kind of cultural narrative, Travels with intertexuality completed the social collective imagination. As the Qing Dynasty Construction of the image, officials try to deviate from the traditional Chinese collective imagination. By virtue of British image of self-desire, they state their self-desire and reflect on their own culture.
