High-Speed Tracking with Kernelized Correlation Filters 的翻译与分析 基于核相关滤波器的高速目标跟踪方法,简称KCF 写在前面,之所以对这篇文章进行精细的阅读,是因为这篇文章极其重要,在目标跟踪领域石破天惊的一篇论文,后来在此论文基础上又相继出现了很多基于KCF的文章,因此文章好比作大厦的基石,深度学习,长短记忆等框架网络也可以在KCF上进行增添模块,并能够达到较好的效果,因此我将深入学习这篇文章,并在此与大家分享,由于学识有限,难免有些谬…

CORRELATION COEFFICIENTS We've discussed how to summarize a single variable. The next question is how to summarize a pair of variables measured on the same observational unit--(percent of calories from saturated fat, cholesterol level), (amount of fe…

Correlation and Regression Sample Covariance The covariance between two random variables is a statistical measure of the degree to which the two variables move together. The covariance captures the linear relationship between two variables. A positiv…

There are three popular metrics to measure the correlation between two random variables: Pearson's correlation coefficient, Kendall's tau and Spearman's rank correlation coefficient. In this article, I will make a detailed comparison among the three…

这些天我在用React和D3做图表,从已经实现的图表里复制了一些坐标轴的代码,发现坐标轴上的n个点里,只有第一个点下面能渲染出文字提示,其余点下面都无法渲染出文字. 和组里的FL一起百思不得其解好几天,其他地方也是这么实现的,为毛这就不好使?格式化函数有问题? 今天HY从TWU回来,我跟她请教这事,HY一听马上说:这是css样式控制的,你看这块,first-child ... 我想说,为啥你没有早点回来跟我pair做这块...…
