Based on the above-mentioned parameter, according to the relationship between robust estimation and nonlinear diffusion, the Turkey loss function is introduced as the diffusion function in SAR image decomposition because of its better performance, and the contour of an image is extracted by the Turkey diffusion function with the proposed diffusion parameter mentioned above. The experiment results indicate that the Turkey loss function based diffusion process can strengthen the conspicuous contour. Additionally, a Raita\'s criterion-based method, solving the automatic diffusion threshold, is proposed to automatically set the threshold in diffusion decomposition.

针对基于梯度参数和局域方差系数的扩散在对SAR图像进行分解时存在的缺陷，提出了一种局域方差系数与窗口幅度均值积的扩散系数，该系数能够更有效地实现潜在目标区域和背景区域的区分；在此基础上，根据鲁棒估计与非线性扩散的联系，引入扩散效果更好的Turkey损失函数作为图像分解中的扩散函数，并结合局域方差系数与窗口幅度均值积的扩散参数来提取图像的轮廓，结果表明：基于Turkey损失函数的扩散过程对特征突出的边缘所起的&强化作用&更加明显；此外，针对扩散分解中的阈值确定问题，提出了一种基于拉依达准则的扩散阈值自动求解方法，实现了扩散阈值的自动求解。

This thesis presents the preliminary study of the influence of sentence stress on prosodic features in Mandarin, and of the relationship between duration and pitch under different sentence stress levels. The results show that: The pitch is the most important factor which carries the sentence stress, with the increase of the sentence stress level, the peak of distribution contour of pitch moves towards high frequency area. In the case of"Stress"and"Light", two peaks are found in the distribution contour of duration, which means that the duration of some words are affected by sentence stress, but of others are not. The relationship between pitch and duration in"Normal","Stress"and"Light" are un-correlated, positive correlation and negative correlation respectively.

研究了汉语语句重音对音长和音高的影响、及音长和音高之间的相互关系，结果指出：（1）音高是汉语语句重音的基本表达手段，随着语句重音级别的提高，音高的统计分布曲线向高频方向推移；（2）在连续语流中的词被&重读&和&轻读&的情况下，音长分布出现双峰，表示它们的音长存在着受语句重音的影响和不受语句重音的影响两种情况；（3）词在&正常&、&重读&和&轻读&三种情况下，音高和音长的相互关系分别是：不相关、负相关和正相关。

Based on the separation technique of address and display, the subfields with higher weight value playing an important role in producing the dynamic false contour are divided into several subfields with lower weight value. The addressing method of accumulation lighting is adopted for the divided subfields. By comparing the gray statistic of input image with the preset gray level thresholds, the operating situation of the dismantled subfield is dynamically determined so as to reduce efficiently the false contour phenomenon without influencing the picture luminance.

该技术基于寻址与显示分离技术，将对产生动态假轮廓起重要作用的权值较大子场拆分为若干个权值较小的子场，并对拆分的子场使用累积发光的寻址方式，利用输入图像灰度统计与预置的灰度阈值比较，动态地确定拆分子场的使用情况，在不影响图像显示亮度的情况下有效地减小了动态假轮廓现象。
