Object Detection

Object detection is a form of supervised learning where a model is trained to identify and categorize objects within images. AutoTrain simplifies the process, enabling you to train a state-of-the-art object detection model by simply uploading labeled example images.

Preparing your data

To ensure your object detection model trains effectively, follow these guidelines for preparing your data:

Organizing Images

Prepare a zip file containing your images and metadata.jsonl.

Archive.zip
├── 0001.png
├── 0002.png
├── 0003.png
├── .
├── .
├── .
└── metadata.jsonl

Example for metadata.jsonl:

{"file_name": "0001.png", "objects": {"bbox": [[302.0, 109.0, 73.0, 52.0]], "categories": [0]}}
{"file_name": "0002.png", "objects": {"bbox": [[810.0, 100.0, 57.0, 28.0]], "categories": [1]}}
{"file_name": "0003.png", "objects": {"bbox": [[160.0, 31.0, 248.0, 616.0], [741.0, 68.0, 202.0, 401.0]], "categories": [2, 2]}}

Image Requirements

• Format: Ensure all images are in JPEG, JPG, or PNG format.

• Quantity: Include at least 5 images to provide the model with sufficient examples for learning.

• Exclusivity: The zip file should exclusively contain images and metadata.jsonl. No additional files or nested folders should be included.

Some points to keep in mind:

• The zip file should contain multiple folders (the classes), each folder should contain images of a single class.
• The name of the folder should be the name of the class.
• The images must be jpeg, jpg or png.
• There should be at least 5 images per class.
• There must not be any other files in the zip file.
• There must not be any other folders inside the zip folder.

When train.zip is decompressed, it creates no folders: only images and metadata.jsonl.
