Setup

First, add jitpack in your build.gradle at the end of repositories:

repositories {
   // ...       
   maven { url "https://jitpack.io" }
}

Then, add the library dependency:

implementation 'com.github.garg-lucifer:AndroidDocumentFilter:0.7.0'

Usage

DocumentFilter documentFilter = new DocumentFilter();

// replace getFilter_Name with the filter you want to use
documentFilter.getFilter_Name(image_bitmap, new DocumentFilter.CallBack<Bitmap>() {
                    @Override
                    public void onCompleted(Bitmap bitmap) {
                        // Do your tasks here with the returned bitmap
                    }
                });

// for example shadow removal
documentFilter.getShadowRemoval(image_bitmap, new DocumentFilter.CallBack<Bitmap>() {
                    @Override
                    public void onCompleted(Bitmap bitmap) {
                        // Do your tasks here with the returned bitmap
                    }
                });
