In general, a JavaFX application will have three major components namely Stage, Scene and Nodes as shown in the following diagram.StageA stage (a window) contains all the objects of a JavaFX application. It is represented by Stage class of the package javafx.stage. You have to call the show() method to ... Read More

In JavaFX, the GUI Applications were constructed using a Scene Graph. A scene graph is a data structure similar to tree, in modern graphical applications. It is the starting point of the application, and it is a collection of nodesTo display something in JavaFX You need to construct a scene ... Read More

Thresholding is a simple technique for the segmentation of an image. it is often used to create binary images. In this the pixels greater than a given threshold value will be replaced with a standard valueIn simple, the threshold value is constant throughout the image.Adaptive thresholding the threshold value is ...

In mask operations the value of each pixel of an image is recalculated based on a given mask matrix, this is known as the kernel. Masking is otherwise known as filtering.The filter2D() method of the Imgproc class accepts a source, destination and kernel matrices and convolves the source matrix with ... Read More
