You can also optionally classify detected objects into one of several\ngeneral categories.\n\nObject detection and tracking with coarse classification is useful for building\nlive visual search experiences. Because object detection and tracking happens\nquickly and completely on the device, it works well as the front end of a longer\nvisual search pipeline. After you detect and filter objects, you can pass them\nto a cloud backend, such as [Cloud Vision Product Search](https://cloud.google.com/vision/product-search/docs/),\nor to a custom model, such as one you trained using\n[AutoML Vision Edge](/docs/ml-kit/automl-vision-edge).\n\n[iOS](/docs/ml-kit/ios/detect-objects)\n[Android](/docs/ml-kit/android/detect-objects)\n| This is a beta release of ML Kit for Firebase. This API might be changed in backward-incompatible ways and is not subject to any SLA or deprecation policy.\n\nKey capabilities\n\nExample results\n\nTracking the most prominent object across images\n\nPhoto: Christian Ferrer \\[CC BY-SA 4.0\\]\n\nMultiple objects in a static image"]]
