Is there a way of setting a region when using Cloud Vision API, more specifically when detecting web entries and pages?
I consider it an important feature as Google search always considers the geo-location of a user when trying to display more relevant pages.
If not, what is the region used when triggering the API?
Thanks for all inputs!
There are two specific questions here and let me attempt to answer that:
what is the region used when triggering the API? : The specific API here is the Vision API. It is possible to restrict the API request/response processing to a specific region. By default, it is a global endpoint but specifically for Text based OCR, you can specify eu or us. Check this link: https://cloud.google.com/vision/docs/pdf#locations.
Specifically for web entities, you cannot set the region while invoking the API. What you could do is to give the API a hint to use geo information in the images and then more relevant search results vis-a-vis the geotagging information available in the images can be returned. The specific element is 'includeGeoResults': true in your request. Check this link: https://cloud.google.com/vision/docs/detecting-web#using_geographic_metadata_with_a_local_image
