Localize and identify multiple objects in a single image

README.md

This flow uses the https://developer.ibm.com/exchanges/models/all/max-object-detector/ deep learning model from the Model Asset Exchange to localize and identify multiple objects in a single image. Refer to the documentation for information about the returned message.

Install the following three modules to run this example flow:

• node-red-contrib-model-asset-exchange
• node-red-contrib-browser-utils
• node-red-contrib-image-output

Note: The object-detector node has been pre-configured to use a hosted model evaluation instance. We recommend using your own local or cloud instance for purposes other than evaluation.
