High Dynamic Range (HDR) - Android

Exposure Fusion Algorithm

Library created for the demonstration of computation of HDR on Android Device. This library uses RenderScript extensively for the computation of pixels.

This Application is provided with beautiful interface, so as to provide the demonstration of the usage of the HDR Library.

Install

In Android Studio users can import the .aar module from the release build / can include the library hdr to their project.

1. Open Project Structure > All Dependencies > + select the .aar file
2. Import the module to the current project & Apply

Usage

Library provides a single way so that multiple request can be sent.

1. In your project import com.adrino.hdr.corehdr.CreateHDR
2. Create instance of the CreateHDR,

        CreateHDR createHdr = new CreateHDR(getApplicationContext());
   

3. Using perform method, perform any action ( intermediate step ) of Exposure Fusion by passing List<Bitmap> consisting of Multiple Exposed Images ( Size should be 3 )

        List<Bitmap> hdrImage = createHdr.perform( bitmapImageList, CreateHDR.Actions.HDR );
   

   Here, CreateHDR.Actions is enumeration which has following items,

        HDR
        CONTRAST
        EXPOSED
        GAUSSIAN
        LAPLACIAN
        NORMAL
        RESULTANT
        SATURATION
   

   Which is used to specify which intermediate result is required. Accordingly the size of output list varies. {see documentation in CreateHDR }
4. Using this list image can be used for further processing.
