Build your own Java apps to Change background in J2K files using server-side APIs.

How to change background in J2K Files Using Java

Frequently, achieving the ideal image requires changing the background. To attain the desired J2K format image effect, foreground objects must be isolated from the rest of the picture. Automatic object detection is possible if the background is uniform. If the photo’s background is uneven or object separation is challenging, pre-marking the image is recommended. This involves identifying rectangular regions within the photo where intended objects reside and specifying their types. This can be done manually or automatically through the Cloud API’s object recognition feature. Following object selection and original background removal, a new background can be applied or transparency can be implemented. In order to change background in J2K 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.
