Kotlin-openCV-filter

Kotlin openCV filter creates operating image manipulation easy and convinient way directly from Kotlin.

The Library is currently in development phase.

Initialization

   lateinit var processImage: ProcessImage
   processImage = ProcessImage.getInstance(this)
   
   class MainActivity : AppCompatActivity(),openCVcallback {
   ....
   
    override fun openCVcallbackMethod() {
      //kotlin-openCV Initialized
    }
   ....

Basic Library Methods

   makeImageBlurry(srcBitmap: Bitmap): Bitmap
   
   makeImageBlurry(srcBitmap: Bitmap, width: Double, height: Double): Bitmap
   
   makeImageBlackAndWhite(srcBitmap: Bitmap):Bitmap
   
   makeImageSharpGaussian(srcBitmap: Bitmap,sigmaX:Double):Bitmap
   
   makeImageSharpGaussian(srcBitmap: Bitmap,sigmaX:Double, sigmaY:Double):Bitmap
   
   makeScaleImage(srcBitmap: Bitmap):Bitmap

Basic Library Method Implementation

 
   processedBitmap = ProcessImage.getInstance(this).makeImageBlackAndWhite(toProcessBitmap)
   

Image Channel Intensity Filters

Another powerful API for this library lets you increase intensity of your image's RGB or HSV value individually as the way you are used with Adobe Lightroom/Adobe Photoshop.

SampleApp includes image manipulation using the API. Operations are very fast. Takes approx 11 sec for 2100 X 1800 pixel image.

   
   ProcessImage.getInstance(context).changeRedIntensity(srcBitmap,percentage):Bitmap
   
   ProcessImage.getInstance(context).changeGreenIntensity(srcBitmap,percentage):Bitmap
   
   ProcessImage.getInstance(context).changeBlueIntensity(srcBitmap,percentage):Bitmap
   
   ProcessImage.getInstance(context).changeHueIntensity(srcBitmap,percentage):Bitmap
   
   ProcessImage.getInstance(context).changeSaturationIntensity(srcBitmap,percentage):Bitmap
   
   ProcessImage.getInstance(context).changeVignettingIntensity(srcBitmap,percentage):Bitmap
