RectLabel vs. Deepen

An offline image annotation tool is designed to support both object detection and segmentation tasks effectively. Users can create various shapes such as polygons, cubic bezier curves, line segments, and points for accurate labeling of images. It also enables the drawing of oriented bounding boxes, particularly useful for aerial imagery analysis. Additionally, the tool allows users to label key points that can be interconnected by skeletons and offers the capability to paint pixels using brushes or superpixels. It ensures compatibility with different machine learning formats by supporting both PASCAL VOC XML and YOLO text reading and writing. Furthermore, users have the option to export their annotated data to CreateML for object detection and image classification tasks, as well as to COCO, Labelme, YOLO, DOTA, and CSV formats. The tool accommodates diverse project requirements by enabling the export of indexed color mask images and grayscale mask images. Users can easily modify settings related to objects, attributes, hotkeys, and fast labeling features to enhance their workflow efficiency. A customizable label dialog allows for smooth integration with attributes, and one-click buttons streamline the selection of object names. With an impressive auto-suggest feature that considers over 5000 object names, users can search for objects, attributes, and image names conveniently in a gallery view. Automatic labeling is facilitated through Core ML models, and the tool includes OCR technology for automatic text recognition. It also offers features to convert videos into image frames and execute image augmentation tasks. Language support covers English, Chinese, Korean, and 11 additional languages, thus catering to a wide-ranging user base and boosting productivity across various regions.
