TLD学习（1）-搭建环境

1. 搭载环境

步骤1：下载Demo: Zdenek Kalal的openTLD，见https://github.com/zk00006/OpenTLD

步骤2：安装Matlab2014b，VS2013，OpenCV2.4.9（需要将dll路径添加到环境变量的path中）

步骤3：设置编译器：mex -setup，选择VS2013

步骤4：修改compile.m，执行

步骤5：执行run_TLD.m

2. 编译

将compile.m文件修改如下（如果想要在cpp中debug，需要在mex后添加'-g'，见点击打开链接）：

3.TroubleShooting

Error: 无法找到"Program Files..."

解决办法：include和libpath中的opencv路径不能有空格。将opencv的安装包extract到别的盘符下，重新cmake一遍，再用vs编译一遍。见《opencv3编程入门》

Error: 错误使用 mex
   正在创建库 lk.lib 和对象 lk.exp
lk.obj : error LNK2019: 无法解析的外部符号 cvAlloc，该符号在函数 mexFunction 中被引用....

解决办法：对于x64系统，需将libpath = 'd:opencvbuildx86vc12lib';改为libpath = 'd:opencvbuildx64vc12lib';

Error: c:Matlabr2014bexternincludematrix.h(266) : error CC4430：缺少类型说明符 -假定为int。注意：C++不支持int

解决办法：

在lk.cpp, fern.cpp, and bb_overlap.cpp中注释掉这些代码： #ifdef _CHAR16_T #define CHAR16_T #endif

Error: bb_overlap.cpp(35) : error C3861: “min”:  找不到标识符

解决办法：修改TLD代码包中mex文件夹下bb_overlap.cpp文件，在头部加上#include "minmax.h"

解决办法：h = FSPECIAL('gaussian',csize,sigma);改为fspecial

Error：Invalid MEX-file 'D:TLDOpenTLD-mastermexlk.mexw64'：找不到指定的模块

解决办法：虽然安装了OpenCV，但是没有将DLL添加到Path中，lk.mexw64（其实也是个DLL）就会找不到关于opencv的DLL。在环境变量->系统变量->Path中添加openCV的dll路径，如d:opencvbuildx64vc12bin. （x64指64位系统，vc12指vs2013），改完后要重启系统。原帖：https://github.com/kyamagu/mexopencv#2-install-opencv-library

解决办法：按空格退出
