# AndroidVisionPipeline
The bare bone pipeline infrastructure required for using google's android vision detectors. Most of the source codes were extracted from [Google's android vision sample](https://github.com/googlesamples/android-vision).
## Pre-Requisite
Android Play Services SDK level 26 or greater.
## Setup
*Gradle*
```groovy
compile 'com.google.android.gms:play-services-basement:latest_version'
compile 'com.google.android.gms:play-services-vision:latest_version'
compile 'online.devliving:mobilevision-pipeline:latest_version'
```
*Maven*
```xml
online.devliving
mobilevision-pipeline
latest_version
pom
```
## Usage
You can add a camera preview with a graphic overlay (to draw stuff over the preview) in xml like this
```xml
```
There are 2 scale types for the preview defined as
```java
public enum PreviewScaleType{
FIT_CENTER,
FILL
}
```
for `FIT_CENTER` the preview will shrink (reduce it's width and height) to meet the aspect ratio of the camera's preview size.
for `FILL` the preview will scale up to fill (may be beyond it's view bounds) and meet the aspect ratio of the camera's preview size.
Overlay graphics that you draw in the `GraphicOverlay` needs to extend the abstract `GraphicOverlay.Graphic` e.g `FaceGraphic` in the sample which draws a rectangle around a face that the `FaceDetector` has detected.
To start the preview and detection you need to provide a `CameraSource` (requires a `Detector` to process the frames) and a `GraphicOverlay`
```java
mPreview.start(mCameraSource, mGraphicOverlay);
```
