Descriptors

Set of data in the base64 format, generated by the CARS_API based on the analyzed characteristics of vehicles.

Vehicle Descriptor Extraction

Vehicle descriptor extraction can be performed using /classify and the «vehicle_descriptor_v2» classifier.

Descriptor Matching for Vehicles

The descriptor matching method is used to determine the similarity between vehicles. It compares images or descriptors and returns a similarity score. The descriptor_matcher method accepts images or descriptors in Base64 format and returns the similarity score of the matched descriptors.

Response example:

{
    "results": [
        {
            "score": 0.9933,
            "execution_time": 0,
            "descriptorVersion": "v2"
        },
        {
            "score": 0.7229,
            "execution_time": 0,
            "descriptorVersion": "v2"
        }
    ]
}
