Pascal VOC XML

Pascal VOC is a common XML annotation format that is human readable but doesn't work with any known object detection models.

Overview

The annotation format originally created for the Visual Object Challenge (VOC) has become a common interchange format for object detection labels. It's well-specified and can be exported from many labeling tools including CVAT, VoTT, and RectLabel.

Unfortunately, no known models directly consume VOC XML labels. That's where Roboflow comes in; it's a universal computer vision format converter that can convert PASCAL VOC into any other format so your data is ready to train in a jiffy.

Split and Merge Datasets

With Roboflow supervision, an open source Python package with utilities for completing computer vision tasks, you can merge and split detections in Pascal VOC XML. Read our dedicated guides to learn how to merge and split Pascal VOC XML detections.

Split detections in Pascal VOC XML


import supervision as sv

ds = sv.DetectionDataset.from_pascal_voc(
    images_directory_path=f"dataset/train/images",
    annotations_directory_path=f"dataset/train/labels"
)

train_ds, test_ds = ds.split(split_ratio=0.7,
                             random_state=42, shuffle=True)
