mser 的全称:Maximally Stable Extremal Regions 第一次听说这个算法时,是来自当时部门的一个同事, 提及到他的项目用它来做文字区域的定位,对这个算法做了一些优化. 也就是中文车牌识别开源项目EasyPR的作者liuruoze,刘兄. 自那时起就有一块石头没放下,想要找个时间好好理理这个算法. 学习一些它的一些思路. 因为一般我学习算法的思路:3个做法, 第一步,编写demo示例. 第二步,进行算法移植或效果改进. 第三步,进行算法性能优化. 然后在这三个过程中

第一,命令模式: (1)用于消除调用者和接收者之间直接的耦合的模式,并且可以对(调用这个过程进行留痕操作) (2)真的不要乱用这个模式,以为他使你简单调用写法变得非常的复杂和有些难以理解. (3)你的业务出现了 (回退操作)(重做操作)的需求的时候你就要考虑使用这个模式了.命令的原理: 一种情况为发出者直接作用于执行者,这样耦合度很高,另外一种情况为,在发出者和执行者之间增加一个用存储命令的命令访问库也即命令命令模式. 第二,现在我们通过一个需求来学习该模式需求为: 1.有一个"添加流程的按钮&
