This article provides guidelines about formats, sizes, etc. of the reference images that you upload to your database, that will help optimize the image recognition performance. Bear in mind that the performance of the overall system depends mostly on the reference images.

Important: We recommend that reference images have any size from
Query images are those sent to the system to search for matches inside a collection.
If you are using one of our SDKs, or libraries, you do not need to worry about the quality of query images. Our SDKs take care of capturing and sending images that give very good recognition results while keeping short round-trip times (e.g. <1s on WIFI or 4G).
