How to capture a photo with a Tensorflow Camera in React native?

TensorFlow.js version

"@tensorflow/tfjs": "^1.5.2",
"@tensorflow/tfjs-react-native": "^0.2.3",

Browser version

"expo": "^37.0.0",
Platform: Android 10
Device: One Plus 8

Describe the problem or feature request

I have a Tensorflow Camera component where I’m running a model every n frames using the onReady = {this.handleCameraStream} type workflow shown in the tensorflow Camera documentation.

I’d like to save a frame of the camera stream as a JPEG depending on the result of the model. Does anybody know the easiest way to do this?

I’ve tried using Expo-Camera’s takePictureAsync function but found that it stops working when you wrap the camera with the cameraWithTensors

Any help would be appreciated!

Any luck figuring out the image quality issue @JJwilkin ?

@tafsiri Hi, thanks for addressing this issue, as I was running into as well. I was working to access the live frames as jpg for OCR purposes, but after decode the tensor into a jpg, found the image quality to be dramatically reduced. My partner had created a stack overflow question detailing this: https://stackoverflow.com/questions/66357352/tensor-to-jpeg-improve-quality
