Binarize DJVU images via Java

How to Binarize DJVU Files Using Java

The invention of color film marked a significant milestone in the realm of photography. However, classical photography is inherently linked to black and white imagery. Despite the extensive technical capabilities of cameras to capture the full spectrum of colors, many individuals opt for monochrome, transforming their pictures into black and white. In such instances, a binarization function comes into play, converting all pixels into binary values: "0" for white and "1" for black. In other scenarios, this conversion isn’t driven by artistic choices but practical ones, like preparing black and white illustrations for printing in books or newspapers. Using the Java graphics library, you can designate a pixel brightness threshold. Pixels with brightness values below this threshold will become black, while those above it will become white. Alternatively, you can employ an adaptive binarization method that considers the pixel values in the surrounding area. This approach results in smoother transitions between color boundaries in the resulting black and white image. In order to Binarize DJVU files, we’ll use Aspose.Imaging for Java API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Java platform. You can download its latest version directly from Maven and install it within your Maven-based project by adding the following configurations to the pom.xml.
