Ambulance dataset needed Could I get a dataset that can classify ambulances? 
I have searched everywhere, but, couldn't seem to get hold of a set of annotated images for ambulances.
Answering my own question here. 

Looked at the Open Image Dataset by Google @ https://storage.googleapis.com/openimages/web/index.html 

They provide image-level labels, object bounding boxes, object segmentation masks, and visual relationships.
