Does Machine Vision API work offline?
<p>Does the Google Mobile Vision (<a href="https://developers.google.com/vision/" rel="noreferrer">https://developers.google.com/vision/</a>) API work offline? Or does it need Internet connectivity? The <a href="https://github.com/googlesamples/android-vision/blob/master/visionSamples/ocr-reader/app/src/main/AndroidManifest.xml" rel="noreferrer">sample app</a> does not require any Internet permission. Which means the API works entirely offline. I am looking for a positive confirmation of this.</p>

<p>PS. Also I am looking for more information on this API. For example, does it use neural networks? If so what algorithms were used? I can not find any detail discussion anywhere. </p>
