It's a package to resize ALL your dataset images (into local folder) and change the pascal_VOC coodinates in your .xml file
- How it works?
- Warnings
- Install requirements
- Usage
- Example
- Folder structure example
- Results
- Parameters
- Walk by paths and searching by .jpg and .xml files
- Resize the image and change the XY coordinates of each object in xml file.
- Save the new files into output path. Folder structure example for more details
- If save_box_images = 1, draw the boundies box in the resized image and save it in an other file(output_path/boxes_images/))
1º: Don't worry about if you has a big folder structure with many folders inside many folders, the package will walk recursively in your dataset folder and recreate the same structure into output_path.
2º: The .jpg and .xml files must be in the same folder
pip install -r requirements.txt
python3 main.py -p <IMAGES_&_XML_PATH> --output <IMAGES_&_XML> --new_x <NEW_X_SIZE> --new_y <NEW_X_SIZE> --save_box_images <FLAG>"
Look this randon folder structure with ALL my dataset

After executed the package with:
python3 main.py -p /home/Ordrix/Pictures/dataset --output ./output --new_x 200 --new_y 200 --save_box_images 1
The package will resize the images, rewrite the xml files and create the same folder structure into output path with new images and xml files.

To know more about parameters use python main.py -h:
usage: main.py [-h] -p DATASET_PATH -o OUTPUT_PATH -x X -y Y
[-s SAVE_BOX_IMAGES]
optional arguments:
-h, --help show this help message and exit
-p DATASET_PATH, --path DATASET_PATH
Path to dataset data ?(image and annotations).
-o OUTPUT_PATH, --output OUTPUT_PATH
Path that will be saved the resized dataset
-x X, --new_x X The new x images size
-y Y, --new_y Y The new y images size
-s SAVE_BOX_IMAGES, --save_box_images SAVE_BOX_IMAGES
If True, it will save the resized image and a drawed
image with the boxes in the images
