Purpose Describe the sum symbol like this: zebk=1Nk∑i∈Rkj∈W(i)∩Rkmax(fi−fj) Solution code z_{ebk}=\frac{1}{N_k}\sum_{\substack{i \in R_k \\ j \in W \left(i \right) \cap R_k}}\max \left( f_i - f_j \right) The key point is the usage of \substack. Refs:…

话不多说,先看图,这是导入一张图后运行的效果. 在此函数中,左图是灰度图加上colorBar后的彩色效果图,右图是二值化后的图,下面是可调节阈值的灰度直方图. 左上角的按钮是回归初始状态,右上角的按钮是结束阈值调整并记录该阈值和所得的二值化图像. 该函数先计算一个自适应阈值,若你不满意可以拉动灰度直方图的阈值灰色竖线左右移动,图像就会根据你的阈值选择变化. 很好用的一个工具,下面放代码. function [level,bw] = thresh_tool(im,cmap,defaultLevel…

行结束符和空白选项 在项目的生命周期中,有时可能会将行结束符由 CRLF 改为 LF,或者修改一段代码的缩进.不幸的是这样将会使大量的代码行被标记为已修改,尽管代码本身并没有被修改.这里列出的选项将会在比较差异 和应用补丁时帮助你应对这些修改.你将会在合并和追溯对话框中看到这些设置,它们同样也出现在TortoiseMerge 的设置中. 忽略行结束符 排除仅行结束符的差异. 比较空白 将所有缩进和行内空白差异视为增加/删除的行. 忽略空白修改 排除那些完全是针对空白数量或类型的修改,例如,修改缩…

Sublime Text 2是那种让人会一眼就爱上的编辑器,不仅GUI让人眼前一亮,功能更是没的说,拓展性目前来说也完全够用了,网上介绍软件的文章和推荐插件的文章也不少,而且很不错,大家可以去找找自己需要的.而且 Linux 支持也做的非常好. 之前想设置什么都是直接在网上搜,但最近想调行距,这个把我给难住了,软件上的设置没找到,网上搜也没有,最后的最后在Sublime的官方论坛找到了,个人觉得行距还是很影响视觉体验的,看看下面的对比图就知道了: 看来想驾驭好这软件不弄清楚配置文件是不行了,周末…

伴随着前期的基础积累,翻过API,读过一些Demo,总觉得自己已经摸透了Prefuse,小打小闹似乎已经无法满足内心膨胀的自己.还记得儿时看的<武状元苏乞儿>中降龙十八掌最后一张居然是空白页,在千钧一发之际以为自己要嗝屁了,一阵东风让苏乞儿明白了,最后一章要做的原来是——整合.没错,今天我们就来好好谈谈整合! 看懂API不代表你会灵活运用某个类,会用一些类不代表能实现小功能,耍的了小功能不一定会做可视化工具整合,整合之道,奥妙无穷! 前篇回顾:上篇<漫谈可视化Prefuse(四)---被…

1.改进算法无论对于那一种程序,好的算法总是非常重要的,而且能够极大地提高程序性能,所以任何性能的优化第一步就是从算法或者说程序逻辑的优化开始,检查自己的程序是否有多余的运算,是否在没有必要的时候做了无用功,往往从这些方面就能找到那些导致性能低下的地方. 2.优化细节代码针对细节总是好的,有一些小技巧比如:用 var obj:Object = {}; 要比 var obj:Object = new Object();要好:var arr:Array = []; 要比 var arr:Array…

很多同学使用 sublime text2 的时候,出现一些奇怪的bug,且重启无法修复. 于是,就会想到卸载 sublime text2 再重新安装. 然而,你会发现,重新安装后,这个bug任然存在,且你之前安装过的插件也都还保留着. 这是因为,卸载的时候只卸载了软件部分,而其配置文件却未被删除. 如果想得到一个全新的 sublime text2 软件,你只需要删除配置文件,重新启动 sublime text2 软件的时候,就会重新生成一个全新的干净的配置文件.就如同你第一次安装 sublime…
