首先看看get_features函数. 首先判断是hog特征还是gray,分两种情况. 如果是hog特征,调用fhog函数,返回x,并将矩阵x的第三维最后一个组数据删除(好奇fhog函数http://vision.ucsd.edu/~pdollar/toolbox/doc/index.html). if features.hog, %HOG features, from Piotr's Toolbox x =…

recently, i need call the KCF tracker in my graduation project. the KCF tracker is fast and best performance now. see http://home.isr.uc.pt/~henriques/circulant/, however, this only matlab version of KCF code in the author's homepage. i need to imple…

Martin Danelljan 判决类追踪模型是由训练样本学习得到,但是为了适应目标和背景的变化sample set在每一帧中都会更新. 令(xjk, yjk)表示第k帧k={1,2,...,t}中的第j个训练样本.假设第k帧中的nk个样本在样本集中, ak表示第k帧样本的权重. 存在一种方法可以控制式子中训练样本的impact.在DCF-based trackers M. Danelljan Accurate scale estimation for robust visual track…
KCF目标跟踪方法分析与总结 correlation filter Kernelized correlation filter tracking 读"J. F. Henriques, R. Caseiro, P. Martins, J. Batista, 'High-speed tracking with kernelized correlation filters'" 笔记 KCF是一种鉴别式追踪方法,这类方法一般都是在追踪过程中训练一个目标检测器,使用目标检测器去检测下一帧预测位置…
读"J. F. Henriques, R. Caseiro, P. Martins, J. Batista, 'High-speed tracking with kernelized correlation filters'" 笔记 KCF是一种鉴别式追踪方法,这类方法一般都是在追踪过程中训练一个目标检测器,使用目标检测器去检测下一帧预测位置是否是目标,然后再使用新检测结果去更新训练集进而更新目标检测器.而在训练目标检测器时一般选取目标区域为正样本,目标的周围区域为负样本,当然越靠近目…
