COCO JSON

What is COCO JSON?

Microsoft released the MS COCO dataset in 2015. It has become a common benchmark dataset for object detection models since then which has popularized the use of its JSON annotation format. You can learn how to create COCO JSON from scratch in our CVAT tutorial.

Unfortunately, COCO format is not anywhere near universal and so you may find yourself needing to convert it to another format for a model (or export to COCO JSON from another format if you happen to be using a model that supports it).

Not to worry, Roboflow is the universal tool for computer vision format conversion and can seamlessly input and output files in COCO JSON format.

What computer vision models use COCO JSON?

The

DETR

YOLOS

Mask RCNN

EfficientDet

Detectron2

models all use the

COCO JSON

data format.

DETR

Detection Transformer (DETR) is an end-to-end object detection model implemented using the Transformer architecture.

YOLOS

YOLOS looks at patches of an image to to form "patch tokens", which are used in place of the traditional wordpiece tokens in NLP.

Mask RCNN

Mask RCNN is a convolutional neural network for instance segmentation.

EfficientDet

EfficientDet achieves the best performance in the fewest training epochs among object detection model architectures, making it a highly scalable architecture especially when operating with limited compute.

Detectron2

Detectron2 is model zoo of it's own for computer vision models written in PyTorch.
