Python utility to work with PascalVoc annotation format
Image examples from [PascalVoc2007](hhttp://host.robots.ox.ac.uk/pascal/VOC/voc2007/) dataset
##### Code Example
```
import json
from pathlib import Path
from PIL import Image
from pascal import annotation_from_xml
from pascal.utils import save_xml
ds_path = Path("/home/VOCtest_06-Nov-2007/VOCdevkit/VOC2007")
img_src = ds_path / "JPEGImages"
ann_src = ds_path / "Annotations"
out_labelme = ds_path / "converted_labelme"
attr_type_spec = {"truncated": bool, "difficult": bool}
label_map = {"car": 1, "dog": 0, "person": 2, "train": 3}
if __name__ == "__main__":
for file in img_src.glob("*.jpg"):
# Get annotation file path
ann_file = (ann_src / file.name).with_suffix(".xml")
# Make pascal annotation object
ann = annotation_from_xml(ann_file, attr_type_spec)
print(ann)
# Save to xml file (same as ann_file)
xml = ann.to_xml()
out_xml_name = file.with_suffix(".xml").name
save_xml(out_xml_name, xml)
# Save yolo annotation
yolo_ann = ann.to_yolo(label_map)
out_yolo_name = file.with_suffix(".txt").name
with open(out_yolo_name, "w") as f:
f.write(yolo_ann)
# Convert to labelme and save json file
res = ann.to_labelme(file, save_img_data=False)
with open((out_labelme / file.name).with_suffix(".json"), "w") as f:
json.dump(res, f, indent=2)
# Draw objects
img = Image.open(file)
draw_img = ann.draw_boxes(img)
draw_img.show()
```
##### Visualization example:
```
draw_img = ann.draw_boxes(img)
draw_img.show()
```
#### Installation
From source
```
python setup.py install
```
Using pip
```
pip install pascal-voc
```
