摘要: ”谈到搜索代码,借鉴前人的劳动,有几个小tricks, 其中之一是选择代码搜索网站,如http://www.koders.com/,http://www.google.com/codesearchhttp://search.ask.com/。还有一个tricks 搜索关键字+语言,如在GOOGLE里键入: segmetation matlab,会出现很多用MATLAB语言写的分割程序。此外GOOLE的论坛、网景公司的Open Directory Project、Mathtool 公司的工具集、MATLAB 公司 File Exchange Corner 以及 SOURCEFORGE都可以找到很 阅读全文

摘要: 最烦的事情莫过于每年的遥感图像处理软件的测评了,这个月逃不掉了,只好坐软件开发方面的工作,其实我自己好喜欢研究算法而不是成熟算法的实现。今天下午和晚上实现了二值和灰度图象的形态学滤波算法的实现。 其中二值图像部分暂且用MATLAB实现的,灰度图部分采用了C#。文献参考:   (1)数字图像处理(MATLAB版)   (2)http://www.codeproject.com/cs/media/Image_Processing_Lab.asp 实现的很丑陋,都不好意思贴出来了:(function out = mydialate;%(inimg, structure)in = imread('bi 阅读全文

摘要: 之一 1。由点到面。选工作实践中的疑点,热点,由一个小枝节,检索较全的文献,一般近期的20 篇左右已经相当多了。之所以不必在意3年以前的,是因为知识更新非常快,且网上能查到的多为近几年的全文。学习别人是怎么发现解决问题的。知道目前对这个问题的共同看法,和分歧。然后,扩展开,根据兴趣和研究的目的,知道,在研究的领域:谁的文章被引用的次数多,谁的文章最多最新最有启发性。去图书馆找他的文章看全文。逐步扩展自己的视野,构建个人的专业知识结构和看法。2。由杂到精。有了一定的知识基础以后,对于繁杂的文献,要有个人的判断。追踪某个专题、某个专家的研究进展,比较对于同一专题的论点的发展,掌握其新的方法或新结论 阅读全文
