项目主页：http://note.sonots.com/SciSoftware/haartraining.html#v6f077ba

项目主页上有编译好的exe文件，但没有Linux下面编译好的二进制文件。

mergevec用于合并多个vec文件。

用法：

[plain] view plain copy

mergevec
<collection_file_of_vecs> #类似于创建样本和训练的描述文件，一个存有要合并的vec文件路径列表的文件，可用find命令查找并重定向生成
<output_vec_filename> #输出vec文件名
[-show] #与创建样本时的show参数一样，
[-w <sample_width = 24>] #不解释
[-h <sample_height = 24>] #不解释

vec2img用于从vec文件中释放图像文件

用法：

[html] view plain copy

vec2img
<input_vec_filename> #指定vec文件
<output_filename_format> #指定输出文件格式，是一个含有%d格式的文件名字串，扩展名决定图像文件的输出格式，如test_%04d.png
[-w <sample_widthsample_width = 24>] #不解释
[-h <sample_heightsample_height = 24>] #不解释

编译：

下载两个文件的源码，因为都是单个文件，这里我贴出来：

编译的话，将两个文件复制到opencv源码中的apps/haartraining/路径下

编译前，代码需要调整一下，将头文件

#include <cvhaartraining.h>
#include <_cvhaartraining.h> // Load CvVecFile

中的<>换成“”，让其在当前路径中寻找头文件，上面我贴出来的代码是已经调整过的。

编译命令：

mergevec.cpp

[plain] view plain copy

$ g++ `pkg-config --cflags --libs opencv` -o mergevec mergevec.cpp cvboost.cpp cvcommon.cpp cvsamples.cpp cvhaarclassifier.cpp cvhaartraining.cpp

vec2img.cpp

[plain] view plain copy

$ g++ `pkg-config --cflags --libs opencv` -o vec2img vec2img.cpp cvboost.cpp cvcommon.cpp cvsamples.cpp cvhaarclassifier.cpp cvhaartraining.cpp
