Compare Two Faces

FindFace Multi allows you to compare two faces and verify that they belong to the same individual.

You may compare two objects from different sources or object with an object within the same card and return the similarity between them.

Do the following:

1. Perform face (car, body) detection on the attached photo and copy id of the necessary object.

2. Use the GET /verify method.

GET /verify

The REQUEST contains QUERY-STRING PARAMETERS:
