This is very simple, and here is a example for image view to get pixels from image and inside if condition you can replace any pixel with a transparent pixel.

Bitmap bitmap = ((BitmapDrawable)imageView.getDrawable()).getBitmap();
int pixel = bitmap.getPixel(x,y);
int redValue = Color.red(pixel);
int blueValue = Color.blue(pixel);
int greenValue = Color.green(pixel);
if(pixel == Color.RED){
    textViewCol.setText("It is RED");
}

Also use a for loop to iterate over the entire bitmap.
