源: 线性代数的本质 内容来自字幕. Let me quote without further comment from Dieudonné's "Foundations of Modern Analysis, Vol. 1" There is hardly any theory which is more elementary than linear algebra, in spite of the fact that generations of professors and te…
Chapter 6 6.1 Inner Products and Norms Definition (inner product). Let V be a vector space over F. An inner product on V is a function that assigns, to every ordered pair of vectors x and y in V, a scalar in F, denoted \(⟨x,y⟩\), such that for all x,…
最近在看有关特征提取的线特征,暑期就看了相关的论文:<基于点线综合特征的双目视觉SLAM方法_谢晓佳>,最近呢,把里面有关线特征提取LSD和描述子LBD的代码跑了一遍,记录如下: [1]LSD: a Line Segment Detector线段检测器 LSD是一种局部提取直线的算法,速度比Hough要快. LSD是一种直线检测分割算法,它能在线性的时间内得出亚像素级精度的检测结果.该算法被设计成可以在任何数字图像上都无需参数调节.它可以自己控制误检的数量:平均而言,每张图有一个误检. 有几篇…
