Setting thresholds interactively

InteractiveThresholding This example demonstrates how to use the SoThresholdingProcessing to create, dynamically a binary image.

The engine's parameter can be set dynamically to get a real time rendering.

DESCRIPTION:

Segmentation is a very important step of an image processing chain. This is where objects to identify in the scene are isolated in a binary or label image.

The example shows how to create a binary image from an input grayscale image setting interactively the threshold values.

• a grayscale image is loaded in an SoImageDataAdapter object,
• the image is then give as input to threshold filter
• User can change threshold value dynamically and see the result
