LabelImg for Labeling Object Detection Data

LabelImg is a free, open-source tool designed for graphically labeling images, particularly useful for object detection models in computer vision. Developed in Python with a QT graphical interface, LabelImg facilitates the accurate labeling of images, which is crucial for creating high-quality datasets that enhance model performance. The tool supports labeling in VOC XML or YOLO text file formats, with VOC XML being recommended due to its universality. Users can manage and convert their datasets into over 26 formats using Roboflow, a cloud-based platform that offers free services for up to 10,000 images, enabling seamless integration into various models. Labeling best practices, such as ensuring complete object coverage and providing clear instructions when outsourcing, are emphasized to ensure the efficacy of the labeled data. Roboflow also offers tools like health checks and model libraries to assist in deploying deep learning models, enhancing the utility of labeled datasets.
