曹帅  ;夏萍  ;冯东  ;夏权  ;殷宗俊 《宜春师专学报》2014,(6):98-101

以新鲜猪肉制品为研究对象,采用图像处理技术检测猪肉在常温下氧化腐败过程中颜色的变化,并使用半微量定氮法与之对比.结果显示：猪肉在腐败过程中,RGB颜色空间变化不明显,HSI颜色空间变化明显;与传统的化学方法检测相比,利用图像的颜色模型可以更加方便快捷的检测猪肉的新鲜程度.  相似文献

MOOC热的冷思考——国际上对MOOCs课程教学六大问题的审思     

高地 《电大教学》2014,(2):39-47

近几年,简称为MOOC的大规模开放在线课程席卷世界高等教育,成为教育研究者关注的焦点问题。但遗憾的是,目前国内相关研究和报道赞扬多,批评少,较系统深入的客观反思性研究则更少见。为此,从“问题的视角”出发．对近年来国内外尤其是美国的学术文献、研究报告、报刊杂志和博客文章进行梳理研究,着重分析了当前MOOC课程完成率不高、教学模式圆于传统、难以实现个性化学习、学习体验缺失、学习效果难以评估、学习成果缺乏认证六个主要问题,以期为MOOC炒作降温、化激情赞扬为冷静审视,把握在线教育发展进程中理想与现实的结合点。  相似文献

Assessing behavioral data science privacy issues in government artificial intelligence deployment     

《Government Information Quarterly》2022,39(4):101679

In today's global culture where the Internet has established itself as the main tool for communication and commerce, the capability to massively analyze and predict citizens' behavior has become a priority for governments in terms of collective intelligence and security. At the same time, in the context of novel possibilities that artificial intelligence (AI) brings to governments in terms of understanding and developing collective behavior analysis, important concerns related to citizens' privacy have emerged. In order to identify the main uses that governments make of AI and to define citizens' concerns about their privacy, in the present study, we undertook a systematic review of the literature, conducted in-depth interviews, and applied data-mining techniques. Based on our results, we classified and discussed the risks to citizens' privacy according to the types of AI strategies used by governments that may affect collective behavior and cause massive behavior modification. Our results revealed 11 uses of AI strategies used by the government to improve their interaction with citizens, organizations in cities, services provided by public institutions or the economy, among other areas. In relation to citizens' privacy when AI is used by governments, we identified 8 topics related to human behavior predictions, intelligence decision making, decision automation, digital surveillance, data privacy law and regulation, and the risk of behavior modification. The paper concludes with a discussion of the development of regulations focused on the ethical design of citizen data collection, where implications for governments are presented aimed at regulating security, ethics, and data privacy. Additionally, we propose a research agenda composed by 16 research questions to be investigated in further research.  相似文献
