Caffe中convert_imageset projrct将图像数据转换成Caffe能读取的数据格式leveldb/lmdb
1.添加命令参数
在main函数中添加命令参数，内容和位置如下：
#ifndef GFLAGS_GFLAGS_H_
namespace gflags = google;
#endif
//convert imageset By XiaopanLyu====================================================
argc = 12;
argv[0] = "convert_imageset";
argv[1] = "-gray=true";//whether read gray image
argv[2] = "-shuffle=true";//whether mix order
argv[3] = "-resize_height=28";
argv[4] = "-resize_width=28";
argv[5] = "-backend=lmdb";//leveldb/lmdb
argv[6] = "-check_size=false";
argv[7] = "-encoded=true";
argv[8] = "-encode_type=jpg";
argv[9] = "E:/MyCode/DL/caffe-master/examples/images/";
argv[10] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/images_list.txt";
argv[11] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/img_convert/";
//after read the [FLAGS] command, the argv & argc would be adjust automatically
//==================================================================================
gflags::SetUsageMessage("Convert a set of images to the leveldb/lmdb\n"
"format used as input for Caffe.\n"
"Usage:\n"
" convert_imageset [FLAGS] ROOTFOLDER/ LISTFILE DB_NAME\n"
"The ImageNet dataset for the training demo is at\n"
" http://www.image-net.org/download-images\n");
gflags::ParseCommandLineFlags(&argc, &argv, true);
.csharpcode, .csharpcode pre

font-family: consolas, "Courier New", courier, monospace;

/*white-space: pre;*/
}
.csharpcode pre { margin: 0em; }

Attention：
1）argv[10] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/images_list.txt";该文件表示的是图像对应的标签，格式如下：
cat gray.jpg 1
cat.jpg 1
cat_gray.jpg 1
fish-bike.jpg 2
2）argv[11] = "E:/MyCode/DL/caffe-master/examples/convert_imageset/img_convert/";该路径下为生成的文件，若之前已经生成过，再次执行代码时要确保没有重复文件，否则会报错。
2.执行代码，得到结果
生成的文件如下：
