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。

By employing the transformations of variables and functions, the exact bright soliton solution on a continuous-wave background is obtained in quadratures, and is discussed in detail. From the behavior of the exact solution in exponential control fiber system, the conclusion can be obtained that soliton in a proper fiber system can be compressed or broadened.
