Annotations we support

With Toloka, you can control data labeling accuracy to build a predictable pipeline of high-quality training data that impacts your CV algorithms. Our platform supports annotation for image classification, semantic segmentation, object detection and recognition, and instance segmentation. Labeling tools include bounding boxes, polygons and keypoint annotation.
Ask Tolokers to draw pixelwise boundaries for each object instance or group of objects.
