Ground-Truth:

• convert xml to our format:

  1. Insert ground-truth xml files into ground-truth/
  2. Run the python script: python convert_gt_xml.py

• convert YOLO to our format:

  1. Add class list to the file class_list.txt
  2. Insert ground-truth files into ground-truth/
  3. Insert images into images/
  4. Run the python script: python convert_gt_yolo.py

Predicted:

• convert darkflow json to our format:

  1. Insert result json files into predicted/
  2. Run the python script: python convert_pred_darkflow_json.py

• convert YOLO to our format:

  1. Add class list to the file class_list.txt
  2. Insert predicted objects files into predicted/
  3. Insert images into images/
  4. Run the python script: python convert_pred_yolo.py

Remove specific char delimiter from files

E.g. remove ; from:

<class_name>;<left>;<top>;<right>;<bottom>

to:

<class_name> <left> <top> <right> <bottom>

In the case you have the --ground-truth or --predicted files in the right format but with a specific char being used as a delimiter (e.g. ";"), you can remove it by running:

python remove_delimiter_char.py --char ";" --ground-truth

Find the files that contain a specific class of objects

1. Run the find_class.py script and specify the class as argument, e.g. python find_class.py chair

Remove all the instances of a specific class of objects

1. Run the remove_class.py script and specify the class as argument, e.g. python remove_class.py chair

Rename a specific class of objects

1. Run the rename_class.py script and specify the --current-class-name and --new-class-name as arguments, e.g.

python rename_class.py --current-class-name Picture Frame --new-class-name PictureFrame

Rename all classes by replacing spaces with delimiters

Use this option instead of the above option when you have a lot of classes with spaces. It's useful when renaming classes with spaces become tedious (because you have a lot of them).

1. Add class list to the file class_list.txt (the script will search this file for class names with spaces)
2. Run the remove_space.py script and specify the --delimiter (default: "-") and --yes if you want to force confirmation on all yes/no queries, e.g.

python remove_space.py --delimiter "-" --yes

Intersect ground-truth and predicted files

This script ensures same number of files in ground-truth and predicted folder. When you encounter file not found error, it's usually because you have mismatched numbers of ground-truth and predicted files. You can use this script to move ground-truth and predicted files that are not in the intersection into a backup folder (backup_no_matches_found). This will retain only files that have the same name in both folders.

1. Prepare .txt files in your ground-truth and predicted folders.
2. Run the intersect-gt-and-pred.py script to move non-intersected files into a backup folder (default: backup_no_matches_found).

python intersect-gt-and-pred.py

Usage of xml2txt.py

• create xml folder to store xml files
• run python xml2txt.py
• a new folder xml2txt will appear automatically to save txt files.
