## Example

To run the example project, clone the repo, and run `pod install` from the Example directory first.

> If this is first time you use [OpenCV-Dynamic](https://github.com/Legoless/OpenCV-Dynamic) as the dependency, it'll take time to install.

## How to Use

Just import the framework

`import SwiftEyes`

In class `SEMotionTrackViewController`, you can see the example.

Simply use the code below can identify the motion blob.

```Swift

func processImage(_ image: OCVMat!) {

// Parameters

let blurSize = 10

let sensitivityValue = 20.0

var differenceMat = OCVMat(cgSize: CGSize(width: image.size.width, height: image.size.height), type: image.type, channels: image.channels)

// from BGR to RGB

OCVOperation.convertColor(fromSource: image, toDestination: image, with: .typeBGRA2RGBA)

// set current mat

currentMat = image.clone()

// convert current mat from RGB to GrayScale

OCVOperation.convertColor(fromSource: currentMat, toDestination: currentMat, with: .typeRGBA2GRAY)

if previousMat != nil {

OCVOperation.absoluteDifference(onFirstSource: currentMat, andSecondSource: previousMat, toDestination: differenceMat)

OCVOperation.blur(onSource: differenceMat, toDestination: differenceMat, with: OCVSize(width: blurSize, height: blurSize))

OCVOperation.threshold(onSource: differenceMat, toDestination: differenceMat, withThresh: sensitivityValue, withMaxValue: 255.0, with: .binary)

}

DispatchQueue.main.sync {

cameraImageView.image = image.image()

displayImageView.image = differenceMat.image()

}

// use previous mat(frame) to compare with next mat(frame)

previousMat = currentMat

}

```
