薄雾影响下的退化彩色图像处理方法

薄雾天气条件下,大气对成像光线的作用使摄取到的彩色图像产生退化,模糊不清,色彩暗淡.在分析这种退化彩色图像成因的基础之上,针对其特点,建立了一种去除此类退化彩色图像中的薄雾影响的图像处理方法,并将模拟大气散射作用的简化模型应用于反锐化掩蔽处理中.与单尺度Retinex算法SSR(singlescale retinex)相结合,在3个尺度上进行了去雾处理,进行颜色恢复和对比度提升.使用了高斯滤波器的无限脉冲响应IIR(infinite impulse response)实现的算法,提高了处理速度.实验结果证明,此方法具有改善薄雾影响的退化彩色图像质量的能力,且处理速度适合于现实的应用.

一种新的n阶纵横图编制的普适方法

纵横图是个古老的组合数学问题。本文以1~n2个连续自然数构成的n行、n列的方形阵列作为n阶纵横图的基数字阵列,研究了其结构特点与纵横图特征(各行、各列及对角线数字和相等)的关系,提出了一种编制任意阶纵横图的通用性方法——对偶数字交换法。应用举例表明,该方法使用便易,不受纵横图的阶数约束,而且易于衍生出诸多种新的纵横图来。     

Is It Better to Forget? Stimulus-Response, Prediction, and the Weight of Past Experience in a Fast-Paced Bargaining Task

Decision makers in dynamic environments such as air traffic control, firefighting, and call center operations adapt in real-time using outcome feedback. Understanding this adaptation is important for influencing and improving the decisions made. Recently, stimulus-response (S-R) learning models have been proposed as explanations for decision makers' adaptation. S-R models hypothesize that decision makers choose an action option based on their anticipation of its success. Decision makers learn by accumulating evidence over action options and combining that evidence with prior expectations. This study examines a standard S-R model and a simple variation of this model, in which past experience may receive an extremely low weight, as explanations for decision makers' adaptation in an evolving Internet-based bargaining environment. In Experiment 1, decision makers are taught to predict behavior in a bargaining task that follows rules that may be the opposite of, congruent to, or unrelated to a second task in which they must choose the deal terms they will offer. Both models provide a good account of the prediction task. However, only the second model, in which decision makers heavily discount all but the most recent past experience, provides a good account of subsequent behavior in the second task. To test whether Experiment 1 artificially related choice behavior and prediction, a second experiment examines both models' predictions concerning the effects of bargaining experience on subsequent prediction. In this study, decision models where long-term experience plays a dominating role do not appear to provide adequate explanations of decision makers' adaptation to their opponent's changing response behavior.

A finite,nonadjacent extreme-point search algorithm for optimization over the efficient set

The problem (P) of optimizing a linear function over the efficient set of a multiple-objective linear program serves many useful purposes in multiple-criteria decision making. Mathematically, problem (P) can be classified as a global optimization problem. Such problems are much more difficult to solve than convex programming problems. In this paper, a nonadjacent extreme-point search algorithm is presented for finding a globally optimal solution for problem (P). The algorithm finds an exact extreme-point optimal solution for the problem after a finite number of iterations. It can be implemented using only linear programming methods. Convergence of the algorithm is proven, and a discussion is included of its main advantages and disadvantages.The author owes thanks to two anonymous referees for their helpful comments.
