Overview

The example demonstrates how to extract color planes from an image.

 

Description

This VI illustrates how to use the IMAQ ExtractSingleColorPane and the IMAQ ImageToArray VIs in order to create an intensity profile of an image. First a color plane from the color image is extracted in order to create a grayscale U8 image. With the 'IMAQ ImageToArray' function the color plane is converted to a 2D Image Pixels array that can be used as an input for the intensity chart.

 

Requirements

 Software

  • LabVIEW 2012 Base Development System (or compatible)
  • Vision Development Module 2012 (or compatible)

 Hardware

  • No hardware is necessary to use this example VI

 

Steps to Implement or Execute Code

  1. (Optional) Select which color plane to extract
  2. Run the VI
