Labels are exported in CSV, JSON. If you want to convert your export to COCO or VOC, check out our conversion scripts here.
For geometric labels (segmentation, key point, etc…) the coordinates are exported in X-Y coordinates.
Labelbox can also export image masks from labels created using the image segmentation tools. Using image masks often means less data preparation is needed to use labels when training machine learning models.
Labelbox generates an image mask per label class (i.e. if there are 2 car and 2 tree labels in an image, 2 image masks in total - a car and a tree - will be created). White pixels in the image mask represent the object.
