 # Drexel Metadata
-Generate Metadata for a fish image using the [hdr-bgnn/drexel_metadata model](https://github.com/hdr-bgnn/drexel_metadata).
+Generate object detection metadata for a fish image using the [imageomics/Drexel-metadata-generator model](https://huggingface.co/imageomics/Drexel-metadata-generator).
 The model will create a visualization based on the image, a mask of the fish outline, and JSON metadata.
+The source code for the model is available at [hdr-bgnn/drexel_metadata model](https://github.com/hdr-bgnn/drexel_metadata).
