I've read How to use the Google Vision API for text detection from base64 encoded image? but it doesn't help at all. Cloud client library is undesirable for me because I am doing many image processing (e.g. rotating, cropping, resizing, etc.) before and during OCR. Saving them as new files and re-read them as inputs of Google Vision API is rather inefficient. Hence, I went check the documentation of posting requests directly: Using Python to send requests Base64 Encoding Optical character recognition (OCR) , and here are minimum codes to make the failure: import base64 import requests import

I am using google vision api for face detection in my app. its working fine but in my case i need to deal with only real human faces. but my app is considering there faces in photo as a face. but i want to detect which is photo and which is live image. below is the class of face graphics private class GraphicFaceTracker extends Tracker<Face> { private GraphicOverlay mOverlay; private FaceGraphic mFaceGraphic; GraphicFaceTracker(GraphicOverlay overlay) { mOverlay = overlay; mFaceGraphic = new FaceGraphic(overlay); } /** * Start tracking the detected face instance within the face overlay. */

we are using google vision ocr for gathering text from receipts. In some cases the receipt have some text written in vertical , like vat information and some other. The question is that google vision read efficiently only the text in the main orientation (horizontal by example) and discards all the text written in the same receipt in vertical orientation instead in horizontal. Is there a parameter to set up for tell google vision to acquire also the text in vertical orientation? I have put online an example with an image with text in two orientations . https://drive.google.com/file/d/0B8kZz

I'm looking to build an app that detects certain objects and then overlays something using ARCore. Is it possible to use Google's Vision API for real-time detection of objects? If not, is there another library that I could use that has object detection, landmark detection, and/or OCR? 来源： https://stackoverflow.com/questions/56031856/using-google-vision-api-with-arcore-in-android

I'm trying to use Google Mobile Vision API with the camera2 module and I'm having a lot of trouble. I'm using Google's android-Camera2Video example code as a base. I've modified it to include the following callback: Camera2VideoFragment.java OnCameraImageAvailable mCameraImageCallback; public interface OnCameraImageAvailable { void onCameraImageAvailable(Image image); } ImageReader.OnImageAvailableListener mImageAvailable = new ImageReader.OnImageAvailableListener() { @Override public void onImageAvailable(ImageReader reader) { Image image = reader.acquireLatestImage(); if (image == null)
