資源簡介
一個基于HoG特征和粒子濾波目標(biāo)跟蹤代碼：
在ivt的基礎(chǔ)上，加入了自己的在線更新機(jī)制 有在線學(xué)習(xí)功能。該算法有以下主要組成：
1、目標(biāo)外觀用多模版的線性組合來表示，組合用最小二乘的方法來求解，文件中有公式推導(dǎo)；
2、特征提取部分使用用opencv完成HoG特征提取的模塊；
3、跟新方法論文：Robust Visual Tracking and Vehicle Classification via Sparse Representation，我也是用這篇文章的思想去做更新機(jī)制的，比較簡單
PS:Hog運(yùn)算部分已經(jīng)生成mex，如果不能運(yùn)行就用你的matlab再編譯生
