关于手写汉字的切分算法的探讨

汉字识别是模式识别的一个重要分支。识别过程包括光电扫描,模数转换,预处理,模式表达,判别。其中预处理阶段的字切分是整个识别过程的一个重要组成部分,也是难点之一,使如污点的处理,粘连问题,字误切后的重新合并问题等,都给我们的准确切分带来许多麻烦。本文以确定的竖写字贴为处理对象,对手写汉字的字切分做了比较细致的工作,特别就以上提高的问题都是提出了比较实际的解决算法,整体上取得了良好的切分效果。     

The link between attractiveness of “Extrabrand” attributes and the adoption of innovations

While innovators may rush to purchase many new products, most consumers are more conservative and do not want to buy into fads but purchase only those new products that are viable. How do the majority of consumers make judgments about whether they will adopt an innovation? This article examines the evaluative aspects of adoption as a means for better understanding consumer adoption and the market factors that may influence the success of an innovation. This research introduces a conceptual model that shows how consumers’ evaluation of product category attractiveness affects the adoption decision for really new products. These consumer evaluations are based on the attributes of the product category (“extrabrand” attributes) rather than brand attributes. Results from a test of the model indicate that consumers do use extrabrand attributes to assess the attractiveness of innovative new products.     

Implications of Improved Information on Market Performance

The retail food market in Edmonton, Alberta represents an unusual market to study. The basic problem inherent in this metropolitan market area of 500,000 people, is the dominance of a single retail food chain whose food sales represent up to 65 percent of total food sales. Conventional economic theory would normally lead to the conclusion that market performance would be improved by a direct attack on the structure of the market which in turn would involve the absolution of a highly successful retail operation. However, the application of monopoly anti-trust laws was certainly not an alternative available to the research team, even if it was considered to be a feasible solution to the problem. Therefore an attempt was made by the authors to observe the impact of improved consumer market information on corporate performance. The following article documents the research and leads towards a time honored conclusion that additional market information would improve consumer welfare in a meaningful manner.
