A fully working example of the OpenCV library used together with React Native.
This tutorial is how to use React Native together with OpenCV for image processing. This example uses native Java and Objective-C bindings for OpenCV. In this example we use the device's camera to take a photo and detect whether the taken photo is clear or blurred.
The examples below show the situation right after taking a photo. The first one shows what happens if we take a blurry photo and the second one is the situation after we took a clear photo and are able to proceed with it to do whatever we want.
