Introduction

This VI uses a 2D array of pixel values between 0 and 255.  The array is converted to an image and displayed.  It, also, checks the pixel value and compares it to a threshold specified by the user.  All pixel values below the threshold are set to 0 (black) and all values about the threshold are set to 255 (white).  The array is then converted to an image and displayed.

Steps to Complete

Enter values between 0 and 255 into the array.  Specify a threshold.  Run the VI.

Additional Notes

None.
