The Smart Annotation Palette is the central interface for all drawing and interaction tasks on the canvas. Unlike traditional labeling environments that restrict a project to a single tool type, this palette provides a versatile toolkit that supports multiple geometry types within the same workspace.
PixlHub allows the label schema to evolve without constant configuration changes. This means a single project is not limited to just one type of annotation (e.g., Bounding Boxes only); managers and annotators can utilize a variety of tools as the project requirements grow.The palette includes the following essential tools:
Bounding Box (BBox): The standard tool for object detection and localization.
Polygon: For high-precision instance or semantic segmentation of complex shapes.
Freeform: A flexible drawing tool for tracing irregular boundaries manually.
Line & Point: Specialized tools for keypoint detection, skeletal structures, or boundary markings.
Comments: A collaboration tool to place feedback markers directly onto specific coordinates.
AI Predictions: An assistive feature that utilizes pre-trained models to generate label suggestions, significantly reducing manual effort.
The primary advantage of the Smart Annotation Palette is its adaptability. New label types can be introduced into an existing project seamlessly. Whether the goal is to add a few keypoints to a bounding box project or to transition into full-scale segmentation, the palette ensures that the workflow remains uninterrupted and the label schema stays flexible.
