在opencv中训练完模型后,可将SVM模型保存为xml文件,可以在实时性应用中通过C++接口调用参数文件,进行实时推断。 SVM继承自StatModel和Algorithm类。在opencv中使用SVM的一般流程如下: 创建模型 语法:cv2.ml.SVM_create()--->retval 作用:创建一个空模型。 配置参数 表格参考自:SVM参数设置总结(参考源码ml.hpp) - ...
MOG算法,即高斯混合模型分离算法,全称Gaussian Mixture-based Background/Foreground Segmentation Algorithm。2001年,由P.KadewTraKuPong和R.Bowden在论文“An improved adaptive background mixture model for real-time tracking with shadow detection”中提出。它使用一种通过K高斯分布的混合来对每个背景像素进行建模的方...

论文原话是:the algorithm first doubles the width and height of its input using bilinear interpolation. That's the first picture above,the one in its own row. 说明:先将图像放大一倍是因为为了尽可能多的保留原始图像信息,所以要先升采样一次。扩大一倍后的图像我们称为Octave-1。但是有时我们也可以不做...
