Image processing in Java

In this article I will introduce you to Java Image processing, explain why Java is a good fit and introduce our JDeli image processing library.

What is Image processing?

Image processing is the action of altering an image using an algorithm. Often this involves a kernel matrix. Image processing operations are frequently used to improve picture quality or expose details as well as just for fun.

Why use Java for Image processing?

Reason 1 ImageIO, plugins and third-party libraries such as JDeli allow Java to read and write a very wide range of Image file formats
Reason 2 Java provides a simple abstract BufferedImage class but also deep level access to pixels, rasters, colorspaces if needed
Reason 3 Graphics2D, kernels and Affine TranformOp allow a very wide range of operations to be applied to an Image.
Reason 4 Java is cross-platform, robust and well supported

Why use JDeli for Java Image processing?

JDeli simplifies image processing in Java and offers the following benefits:

• prevent heap related JVM crashes
• large selection of predefined Image processing operations
• custom() operation makes it easy to define new operations
• support for additional image formats such as Heic
• reduce output file size
• improve read/write performance
• create smaller files
• control over output
• support threading
• superior image scaling algorithms

Are there any other tutorials showing how to use JDeli to process images?

• How to resize images in Java
• Image Rotation in Java
• Image Scaling in Java
• Image Scaling options in Java
