alpha nueric characters detect

这是一本关于matlab的书籍，对初学者很有帮助(This is a book on matlab, helpful for beginners )

说明：  this program used to detect skin in image and this is the main code that is use to detect any presence of human.

利用MATLAB实现屏蔽电缆转移阻抗解析法S.Sali模型，已调通。希望对大家有帮助，也可以用来学习MATLAB编程。(Use of MATLAB shield cable transfer impedance analytic method S.S ali model, has the expert. We want to help, but also can be used to study the MATLAB programming.)

说明：  现代海战需要功能综合的作战平台和性能优良的 武器系统来应对，海战场复杂多维的环境因素对海上 兵力运用有很大的影响。因此，如何准确建立海战场 的评估指标体系并进行科学评判是指挥员做出决策的 重要前提。目前，海战场环境评估的方法有层次分析 法、模糊评判法、指数法等11’21。针对这些方法主观性 比较强等不足，本文引入云重心的评估方法简单易行， 科学有效，可操作性强。 基于云重心方法的海战场环境评估(Modern naval warfare needs integrated operational platforms and excellent weapon systems to cope with. The complex and multi-dimensional environmental factors of naval battlefield have a great impact on the use of naval forces. Therefore, how to accurately establish the evaluation index system of sea battlefield and make scientific evaluation is an important prerequisite for commanders to make decisions. At present, the methods of Marine Battlefield Environment Assessment include analytic hierarchy process, fuzzy evaluation, index method and so on. In view of these shortcomings, such as strong subjectivity, this paper introduces cloud gravity center evaluation method which is simple, scientific and effective, and operable.
