彩色汽车牌照定位方法

汽车牌照的定位是牌照识别的第一步，定位的准确与否将后续操作起关键性的作用。在模式识别领域中，希望通过一种方法就完成一项实际工作是不可能的，必须要考虑多种方法融合的策略，提出了一种基于多方法的车牌定位策略，首先利用颜色信息对输入图像进行彩色粗分割，得到了颜色为车牌照的一些区域，然后将分割结果中的伪目标区域（即除了车牌照区域外的其他区域）分为两类（一类是与汽车牌照颜色相近的背景，一类是可能和牌照颜色相近的汽车外壳），分别进行处理，最终利用投影法得到准确的车牌位置，实验结果表明该方法效果较好。     

"Men, family-role quality, job-role quality, and physical health": Correction to Barnett and Marshall.

Reports an error in "Men, family-role quality, job-role quality, and physical health" by Rosalind C. Barnett and Nancy L. Marshall (Health Psychology, 1993[Jan], Vol 12[1], 48-55). In this article the title for Table 1 (p. 50) should be "Correlations Between Rewards and Concerns in the Job, Marital, and Parent Roles." Also, the last item in the first column of the table should read "6. Parent-role concerns." (The following abstract of the original article appeared in record 1993-21527-001.) The relationship between the quality of family roles, as spouse and as parent, and the quality of men's job role, on the one hand, and their reports of physical symptoms, on the other, was examined in men drawn from a random sample of 300 dual-earner couples. The main effect of marital-role quality (i.e., rewards and concerns) on physical health was estimated, as was the Marital-Role Quality × Job-Role Quality interaction effect. With respect to the present role, the effect of both parent-role occupancy and parent-role quality was estimated. After controlling for job-role quality, it was found that parent-role occupancy had neither main nor interactive effects. However, among the men who occupied all 3 roles (n = 180), only parent-role concerns were a significant predictor of physical health reports. Thus, concerns in the parent role are a major unmeasured source of variance in studies of the stress-illness relationship in men. [An erratum concerning this article appears in Health Psychology, 1993(Mar), Vol 12(2), 92. Table 1 is corrected.] (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

电视图像噪声测量分析评价仪

人们普遍采用CCIR第500-Ⅰ号建议书推荐的主观评价法确定电视图像质量的好坏。本文介绍一种电视图像噪声测量分析评价仪,并对其系统设计及试验作了详细论述。文章着重介绍了针对活动图像噪声处理难点采用的噪声移动处理法以及根据人的主观评价模型系统采用的电视图像噪声的自相关分析、功率频谱估计等方法。该系统外围接口简单。上述全部功能均在IBM-PC/XT上编程实现。
