Java OpenCV Programs – Basic to Advanced

Last Updated : 25 Aug, 2023

Java is a popular programming language that can be used to create various types of applications, such as desktop, web, enterprise, and mobile. Java is also an object-oriented language, which means that it organizes data and behaviour into reusable units called classes and objects. Java is known for its portability, performance, security, and robustness.

OpenCV is an open-source library that provides a comprehensive set of computer vision and machine learning algorithms. OpenCV can be used to perform tasks such as face detection, object recognition, image segmentation, optical flow, feature extraction, and more. OpenCV supports multiple programming languages, including C++, Python, and Java.

This article provides a variety of Java OpenCV programs that you can use to learn how to use the library in your own applications.
