Pascal VOC XML to YOLO Darknet TXT Annotations Converter

YOLO Darknet TXT Annotations Format

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

Where:

<object-class> - integer number of object from 0 to (classes-1)

<x> <y> <width> <height> - float values relative to width and height of image, it can be equal from (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)

For example for img1.jpg you will be created img1.txt containing:

1 0.716797 0.395833 0.216406 0.147222
0 0.687109 0.379167 0.255469 0.158333
1 0.420312 0.395833 0.140625 0.166667
