PartⅡ. Dickinsons Letters from John Chinaman(also titled Letters from a Chinese official: beingan eastern view of western civilization) depicted the image of China superior to the occidentalworld in religion, social system, civilian life, art and aesthetics by contrasting Chinese andoccidental civilization. The author made use of the image of China as background to criticize Britishsociety, point out the obvious problems and latent crisis, refute the sayings in the Occident whichregarded China as yellow peril, an uncivilized nation.

第二部分。狄金逊的《约翰中国佬》(又名《中国官员来信：对西方文明的看法》)通过中西文化、文明对比的方式，塑造了在思想信仰、社会制度、民众生活、艺术审美等方面均优越于西方的乌托邦式的中国形象，以此来批判英国社会、揭示其存在的危机和弊端。

Both the theoretical analysis and experimental results validate that the proposed Laplacian construction approach can better capture the intrinsic structure between image pixels, and can propagate the finer ingredients of an image foreground and background rather than just their labels, and thus the mattes of higher quality are obtained.

D entropic thresholding method is a common image segmentation technology,it is suitable for the image segmentation of the object and background occupying the vast majority region of 2-D histogram,but this approach neglects the information of edge regions to the results of the segmentation.

二维熵的图像分割方法是一种常用的阈值分割技术，适合于对象和背景占据二维直方图绝大部分区域的图像分割，但该方法忽略了边界区域的信息对分割结果的影响。

The proposed algorithm comprehensively considers the effects of local area average brightness of the background and space complexity on visual resolution. In order to judge whether the variance of gray is effectively percepted or not, the just noticeable difference is derived. The changes in the number of perceptible pixels between the original image and the enhanced image can be calculated by use of JND parameter. Thus quantitative results to assess the quality of enhanced images are obtained.

算法综合考虑图像局部区域的背景平均亮度和空间复杂度对视觉分辨力的影响，导出了用于判断局部灰度级跃变是否被有效感知的重要参数―临界可见偏差JND，并利用此参数分别计算出图像增强前后有效感知像素数的变化情况，从而定量地给出图像增强质量的评价结果。
