Car Parts Recognition and Segmentation
Car Parts Recognition and Segmentation
You can now submit one or more images of a vehicle, and obtain the coordinates of all the car body parts detected in the image.
Output image is for illustrative purposes only. The part masks must be drawn using the polygon coordinates provided in the JSON.
