2Label - Annotation Format Conversion Tool

A comprehensive toolkit for converting between various image annotation formats

Overview

2Label is a toolkit designed to simplify the process of converting between different annotation formats used in computer vision and image labeling tasks. It supports conversions between popular annotation tools like CVAT, LabelImg, LabelMe, VIA, COCO, YOLO, and more.

Features

• Multiple Format Support: Convert between various annotation formats
• Batch Processing: Process multiple files at once
• Data Integrity: Preserves annotation data during conversion
• Extensible: Easy to add support for new annotation formats
