Convert YOLO to Pascal VOC format or Pascal to YOLO format

Usage:

git clone https://github.com/yakhyo/yolo2voc.git
cd yolo2voc
pip install -r requirements.txt

• Modify variables in config.py based according to your dataset
• Run python main.py --yolo2voc to convert YOLO to VOC
• Run python main.py --voc2yolo to convert VOC to YOLO
• Run python main.py --voc2yolo_a to convert VOC to YOLO (absolute)

Pascal VOC To YOLO

main.py --voc2yolo

• <object-class> - integer number of object from 0 to (classes-1)
• <x> <y> <width> <height> - float values relative to width and height of an image, it can be within range of (0.0 to 1.0]
• For example: <x> = <absolute_x> / <image_width> or <height> = <absolute_height> / <image_height>
• Attention: <x> <y> - are center of rectangle (are not top-left corner)

The label file corresponding to the above image contains 2 persons (class 0) and a tie (class 27):

<object-class> <x> <y> <width> <height>

Pascal VOC To YOLO Absolute

main.py --voc2yolo_a

• <object-class> - integer number of object from 0 to (classes-1)
• <x_min> <y_min> <x_max> <y_max> - int absolute values object coordinates
• For example: <object-class> <x_min> <y_min> <x_max> <y_max>:
