Windows & Linux GUI for marking bounded boxes of objects in images for training Yolo v2

• To compile on Windows open in MSVS2013/2015 yolo_mark.sln, compile it and run the file: x64/Release/yolo_mark.cmd (if your version other than OpenCV 2.4.9 - change version number in 3 lines by [this link] (https://github.com/AlexeyAB/Yolo_mark/blob/746e590b106080dbb3d205dd453b2fcea5e880a3/main.cpp#L1) )

• To compile on Linux type in console 3 commands:

  cmake .
  make
  ./linux_mark.sh
  

1. To test, simply run

• on Windows: x64/Release/yolo_mark.cmd
• on Linux ./linux_mark.sh

2. To use for labeling your custom images:

• delete all files from directory x64/Release/data/img
• put your .jpg-images to this directory x64/Release/data/img
• change numer of classes (objects for detection) in file x64/Release/data/obj.data: https://github.com/AlexeyAB/Yolo_mark/blob/master/x64/Release/data/obj.data#L1
• put names of objects, one for each line in file x64/Release/data/obj.names: https://github.com/AlexeyAB/Yolo_mark/blob/master/x64/Release/data/obj.names
• run file: x64\Release\yolo_mark.cmd

3. To training for your custom objects, you should change 2 lines in file x64/Release/yolo-obj.cfg:

• set number of classes (objects): https://github.com/AlexeyAB/Yolo_mark/blob/master/x64/Release/yolo-obj.cfg#L230
• set filter-value equal to (classes + 5)*5: https://github.com/AlexeyAB/Yolo_mark/blob/master/x64/Release/yolo-obj.cfg#L224

3.1 Download pre-trained weights for the convolutional layers (76 MB): http://pjreddie.com/media/files/darknet19_448.conv.23

3.2 Put files: yolo-obj.cfg, data/train.txt, data/obj.names, data/obj.data, darknet19_448.conv.23 and directory data/img near with executable darknet-file, and start training: darknet detector train data/obj.data yolo-obj.cfg darknet19_448.conv.23
