The method includes steps: digital watermark technique is adopted to hide information of key data in not key data codes of compressed image; under protection of digital watermark, using protective backup for key data detects whether normal transmitted key data is correct or not so as to detect error code; carrying out cyclic mutual backup by using macro blocks in same positions in front and back macro block set; embedding coded motion vector in form of digital watermark to DCT transformation coefficient, and ensuring that video data are not influenced as best as one can; when error code occurs, if key data backup is correct, then the backup replaces former key data; otherwise, using mean value of key data in adjacent macro blocks within same frame to replace former key data approximately.

本发明中，采用数字水印技术在压缩图像的非关键数据编码中隐藏关键数据信息；通过数字水印保护下的关键数据保护备份来检测正常传输的关键数据是否正确，由此来检测传输误码；用前后宏块组中相同位置的宏块进行循环相互备份；对运动向量进行编码，然后以数字水印的形式嵌入到相对不重要的DCT变换系数中，同时保证视频数据尽量不受影响；在误码发生时，如果关键数据备份正确，则直接替代原关键数据，否则用同一帧内相邻宏块的关键数据的平均值近似替代原关键数据。

It also shows that studying those associates would enhance semantic, but not perceptual processing of lures which verifies the discrepancy-attribution hypothesis.2, Compared with those emotional lures and associations in the unrelated lists, participants produce significant false recognition of emotional lures, even though initially no emotional lures appeared in the phonetic or pictophonetic relatedness effects.3, Participants show no significant difference to the emotional and nonemotional lures after studying phonetic or pictophonetic associations of single character Chinese, while phonetic relatedness effects of two-character Chinese words in the phonetic shows.

而本研究试图系统的探讨汉字关联效应中对情绪诱词的错误再认情况，本研究的结果表明： 1、在语义关联下，被试对中性、正性、负性的关键诱词都引发了很高的记忆错觉，表明这种实验范式对未出现的关键诱词的诱发错误再认是很强烈的；同时实验结果表明，对学过词表的关键诱词的知觉加工没有促进，而促进了对关键诱词的概念加工，验证了差异归因假设。

According to a thorough comparison and analysis of several classical criticality indexes including Path Criticality Probability, Activity Criticality Probability, Activity 'Cruciality' Index, all these indexes have limitations and pitfalls to some degree. Therefore, Activity Compound Criticality Index is presented as a compound index of ACP and ACI, and on the basis of ACCI, Project Compound Criticality Index, a new index that reflects the criticality of a whole project or subproject is proposed.

首先，对几个经典关键性指标——线路关键概率(Path Criticality Probability， PCP)、工序关键概率(Activity Criticality Probability， ACP)和工序关键指标(Activity Cruciality Index， ACI)——进行比较研究；鉴于各自利弊，提出一个 ACP 与 ACI 的整合指标——工序复合关键指标(Activity Compound Criticality Index，ACCI)，并进一步提出了一个表征项目整体&关键&水平的新指标项目——复合关键指标(Project Compound Criticality Index， PCCI)。

Firstly, the key frames were extracted from the video sequence. Then, the features detected between adjacent key frames were guided and matched by motion displacement, which was calculated by the optical flow field. With the RANSAC robust estimation and cascade of homography matrix, the homography matrix of the adjacent key frame and the nonadjacent key frame was got. Finally, the seamless mosaic was rendered by image blending.

首先在同一镜头下的视频序列中提取若干关键帧，利用关键帧拼接表示序列的拼接；其次利用光流场算法计算出的运动位移量引导相邻关键帧间特征点的匹配，并结合随机抽样一致性鲁棒估计算法和单映矩阵的级联性，得到相邻关键帧、非相邻关键帧间的对应矩阵；最后通过融合实现了序列的无缝拼接。

The 352 valid samples were analyzed by SPSS. The results showed there was no distinct corresponding relationship between the product attributes and reaction time. The different key attributes from questionnaire importance rating and the shortest reaction time standards were used to regressively analyze the results of customers' overall rating (such as overall satisfaction,objective quality, recommend intention).The results indicated that the coefficiency of regression of the special attributes chosen from reaction time to overall rating was distinct, while the coefficiency of the special attributes chosen from importance rating to overall rating was not. The main conclusions are: 1. Regarded attributes can be obtained by the reaction time of brand performance rating.

本实验的有效样本为352个，通过SPSS软件进行分析统计，数据统计结果显示，在品牌表现评价反应时与其重要性问卷评定结果的相关系数的检验中，并未发现品牌表现评价反应时与品牌属性重要性评定结果之间的显著相关；将由问卷重要性评价最高标准所得到的关键属性与通过品牌表现评价反应时最短的标准所选取的关键属性的品牌表现分别对消费者的总体评价结果（如&总体满意度&、&主观质量&、&推荐意向&）进行回归分析，发现通过品牌表现评价反应时方法选取的特殊关键属性（与问卷重要性评定法选取不一致的关键属性）的品牌表现对总体评价结果的回归系数显著，而重要性评定问卷法选取的特殊关键属性（与品牌表现评价反应时法选取的不一致的关键属性）的品牌表现对总体评价结果回归系数不显著。
