[Vivek_N]

Overview

This example demonstrates how to threshold an IMAQ image and show the result as a mask in the image

Description

This example opens an image file, performs a threshold on it and shows the threshold result as a mask on the original image.

Requirements

 Software

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

 Hardware

• No hardware is necessary to use this example VI

Steps to Implement or Execute Code

1. Download and open the attached file
2. Run the program

Additional Information or References

Note: If your taps are interlaced vertically, use Transpose 2D Array to rotate your image after IMAQ ImageToArray and use an additional Transpose 2D Array to rotate your image before the final IMAQ ArrayToImage.

For color images use IMAQ ColorImageToArray and IMAQ ArrayToColorImage in place of IMAQ ImageToArray and IMAQ ArrayToImage, respectively. Be sure to change the Image Type of IMAQ Create if your image is not 8-bit grayscale. IMAQ ColorImageToArray and IMAQ ArrayToColorImage are available in NI Vision Development Module.
