Overview
How to remove background in DJVU Files Using Java
Removing the background from an image involves isolating foreground objects, a task that requires object recognizing. Multiple approaches exist to identify objects within a photo in DJVU format. For simple images featuring a uniform color background, an automatic method suffices. However, for photos with multiple or partially merged figures, pre-marking objects becomes necessary. This involves specifying rectangular regions and object types for removal. In intricate cases, the Cloud API enables automatic object detection. The Cloud API provides a cloud application capable of recognizing objects within photos, leveraging the resulting contours for background removal. Post-removal, edges left behind by figures can be smoothed to enhance image quality. In order to remove background in 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.

About Aspose.Imaging for Java API
Aspose.Imaging API is an image processing solution to create, modify, draw or convert images (photos) within applications. It offers: cross-platform Image processing, including but not limited to conversions between various image formats (including uniform multi-page or multi-frame image processing), modifications such as drawing, working with graphic primitives, transformations (resize, crop, flip&rotate, binarization, grayscale, adjust), advanced image manipulation features (filtering, dithering, masking, deskewing), and memory optimization strategies. It’s a standalone library and does not depend on any software for image operations. One can easily add high-performance image conversion features with native APIs within projects. These are 100% private on-premise APIs and images are processed at your servers.Remove background in DJVU via Online App

DJVU What is DJVU File Format
DjVu, pronounced as “déjà vu”, is a graphics file format intended for scanned documents and books especially those which contain the combination of text, drawings, images and photographs. It was developed by AT&T Labs. It uses multiple techniques like image layer separation of text and background images, progressive loading, arithmetic coding and lossy compression for bitonal images. Since DJVU file can contain compressed yet high-quality colour images, photographs, text, and drawings and can be saved in less space therefore, it's used on web as eBooks, manuals, newspapers, ancient documents, etc.
