php使用face++实现一个简单的人脸识别系统
文件目录：
dir.php
\n";
while($file = $mydir->read())
{
if((is_dir("$directory/$file")) AND ($file!=".") AND ($file!=".."))
{
echo "$file \n";
tree("$directory/$file");
}
else
echo "$file \n";
}
echo "\n";
$mydir->close();
}
//开始运行
//echo "目录为粉红色
\n";
//tree("D:\\AR");
/***********************
第二种实现办法：用readdir()函数
************************/
function listDir($dir, &$names, &$img_urls)
{
if(is_dir($dir))
{
if ($dh = opendir($dir))
{
while (($file = readdir($dh)) !== false)
{
if((is_dir($dir."/".$file)) && $file!="." && $file!="..")
{
//echo "文件名：",$file,"
";
listDir($dir."/".$file."/");
}
else
{
$file = iconv("gb2312","UTF-8",$file);
if($file!="." && $file!="..")
{
//echo $file."
";
//var_dump($file);
$file_name = strstr($file, '.', true);
//echo $file_name."
";
array_push($names, $file_name);
array_push($img_urls, $dir."/".$file);
}
}
}
closedir($dh);
}
}
}
//开始运行
//$file_names = array();
//listDir("E:\\test", $file_names);
//var_dump($file_names);
//$name = array("叶子", "朱镇模");
//echo $name[0];

使用说明：
训练部分：
1.训练只需要做一次就可以
2.如果训练目录中的图片发生了改变，则需要再训练一次
3.需要联网才可以使用啊
4.训练时需要选择训练用的目录
5.训练目录中每个人的图片都有一张就可以
6.命名时用英文命名
测试部分：
1.测试时选择一张图片后输入即可
2.请在recognition.php页面中使用$person_name变量
记录好英文文件名与中文人名的对应
3.比如$person_name = array("ami" => "艾米",
"dongjian" => "张东健", "xiaowang" => "小王");
4.'=>'前的是训练时的英文文件名，
箭头后边的则是这个英文名对应的中文名
