想搞下追踪的东西，opencv的opencv_contrib包中有类似的tracking可用

在编译好opencv3.1.0的基础上继续执行下面即可

1。下载 选择对应版本

cd /home
git clone https://github.com/Itseez/opencv_contrib.git
cd opencv_contrib
git checkout 3.1.0  #我使用的是opencv3.1 注意opencv_contrib 要和你的opencv相对应

2。安装opencv_contrib模块

cd ~/opencv-3.1.0/build
cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local -D OPENCV_EXTRA_MODULES_PATH=/home/yourname/opencv-3.1.0/opencv_contrib-master/modules/ ..

# 上述无报错，开始安装！
make -j8
sudo make install -j8

ubuntu 14.04 64位安装Opencv3.1.0+包含opencv_contrib模块

报错:fatal error hdf5.h no such file or directory
这里写图片描述
解决办法：
在opencv-3.1.0/modules/python/common.cmake首行添加如下代码：

find_package(HDF5)
include_directories(${HDF5_INCLUDE_DIRS})

遇到的报错

解决方案：

# 打开问题文件
gedit ~/opencv_contrib/modules/tracking/include/opencv2/tracking/onlineMIL.hpp 

# 修改代码
# 找到下面这一行
#define sign(a) a > 0 ? 1 : a == 0 ? 0 : -1

替换为
namespace {
    template<typename T>
    CV_INLINE int sign(const T v) {
        return (v > 0) ? 1 : ((v < 0) ? -1 : 0);
    }
} // anon namespace


# 然后重新
make -j8
sudo make install -j8
