## Introduction

This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the style transfer model.
1. This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the style transfer model. (tflite model)

- The topmost view is the preview image of the camera.
- The bottom view shows style transferred image of the camera input.
- The applied style changes after several seconds.

2. This is a simple example to show how to use NNStreamer APIs and Android Camera API to utilize the image classification model. (MXNet model)

- The topmost view is the preview image of the camera.
- The bottom view shows the camera input and its classification result on the screen together.
- The applied classification results change directly as the camera screen changes.
