Scalabel vs. Ango Hub

Enable a diverse range of annotation types for images and videos through a versatile, open-source web tool. This platform is built to scale effectively and features user-friendly “click and drag” capabilities that simplify the process of adding numerous attributes. It includes functionalities that allow the fitting of boundaries with Bezier curves and the option to duplicate common boundaries, enhancing efficiency. Users can pinpoint the specific areas where a driver is active and delineate lane lines, which is crucial for improving vision-based vehicle localization and trajectory planning. An easy four-click approach is utilized to precisely encapsulate objects of interest, while sophisticated algorithms leverage object tracking and interpolation methods to forecast annotations across different frames for bounding boxes. The tool also extends its prediction capabilities to individual object instances, with 2D tracking that has been further developed into a three-dimensional framework, thereby enriching the overall annotation experience. By incorporating these advanced features, this tool strives to optimize the workflow for individuals engaged in tasks related to image and video annotation, ultimately leading to enhanced productivity and accuracy. Furthermore, the platform's adaptability ensures that it can cater to the evolving needs of various users in this field.
