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…

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…

本文把自己理解的图像存储格式总结一下. 计算机中的数据,都是二进制的,所以图片也不例外. 这是opencv文档的描述,具体在代码里面,使用矩阵来进行存储. 类似下图是(BGR格式): 图片的最小单位是像素,这里是BGR(通常我们说的blud.green.red的表示法)表示每个像素对应的值(这里BGR的混合,可以得到我们可见光的所有值). 如果是单通道(例如:灰度化之后的图像,这里就只有一列) 参考可见光光谱: 因为物体都是原子组成,原子都在运动,运动会产生光波,不同的物体生成的光波不一样,人类…
