课程大纲:http://vision.stanford.edu/teaching/cs131_fall1718/syllabus.html 课程定位: 课程交叉: what is (computer) vision?: 1. a scientific field that extracts information out of digital images. 2. building algorithms that can be understand the contnent of image a…

大纲 what is color? The result of interaction between physical light in the environment and our visual system. A psychological property of our visual experiences when we look at objects and lights, not a physical property of those objects or lights. Hu…

向量和矩阵 什么是矩阵/向量? Vectors and matrix are just collections of ordered numbers that represent something: movements in space, scaling factors, pixel brightness, etc. We'll define some common uses and standard operations on them. 向量:列向量/行向量 用处: Vectos can…

实在是太喜欢Richard Szeliski的这本书了.每一章节(after chapter3)都详述了该研究方向比較新的成果.还有很多很多的reference,假设你感兴趣.全然能够看那些參考论文 Point operators(点算子) 点运算是最简单的一类图像处理运算.如简单的对照度变换,亮度变换 Pixel transform(像素变换) g(x) = af (x) +b    a和b有时被觉得用来控制对照度和亮度,在我的opencv栏目有个样例是简单的对照度和亮度变换,用的就是这个公式…

一.区域—麻雀虽小,五脏俱全的迷你MVC项目 1.1 Area的兴起 为了方便大规模网站中的管理大量文件,在ASP.NET MVC 2.0版本中引入了一个新概念—区域(Area). 在项目上右击创建新的区域,可以让我们的项目不至于太复杂而导致管理混乱.有了区域后,每个模块的页面都放入相应的区域内进行管理很方便.例如:上图中有两个模块,一个是Admin模块,另一个是Product模块,所有关于这两个模块的控制器.Model以及视图都放入各自的模块内.可以从上图中看出,区域的功能类似一个小的MVC项…

项目忙,趁着刚才有点空,看了下触摸事件在新版本中怎么实现,遇到问题都是去:cocos2d-x-3.1.1\tests\cpp-tests\Classes下面找的,里面都是一些小例子. 首先新的CCNode自带了一个 _eventDispatcher:EventDispatcher, 和ActionScript 3 里面的EventDispatcher是一个词,所以可想而知,功能应该是一致的,其职责应该是事件的分发与接收,后续可以研究下它是否支持时间冒泡. 在之前的init()中加入如下代码,可以…

In the 1960s, the legendary Stanford artificial intelligence pioneer, John McCarthy, famously gave a graduate student the job of “solving” computer vision as a summer project. It has occupied an entire community of academic researchers for the past 4…
