OpenCV is a cross-platform library used to develop real time computer vision applications. OpenCV mainly focuses upon Image Porcessing, Video Capturing and analysis including Face detection and Object Detection.

To work with OpenCV in java, A programmer should have a prior knowledge of Java Programming Language and JavaFX for GUI.

There are a lot of features of OpenCV Library, as follows:

1. Read and Write Images.
2. Capture and Save Images.
3. Processing of Images.
4. Perform Feature Detection.

and many more.

OpenCV can be used in many fields like :

Medicine Applications.

Classification and detection can be useful for cell classification and tumor detection.

Security Applications.

Can be very useful in Surveillance program detecting suspicious activities. Bio metrics like Face detection, iris, eye and Finger print.
