Overview

This VI demonstrates a way to overlay a grid of rectangular ROIs onto an image.

 

Description

This example shows a way to overlay a grid of rectangular ROIs onto an image. It allows the user to define the number of rows and columns for the grid, and then defines and overlays the ROIs automatically. Using the selected image's size, and the user's row and column number inputs, the program determines the coordinates necessary for the top left, and bottom right locations of each rectangular ROI. It then converts this rectangle into an ROI and overlays it on the image.

 

Requirements

  • LabVIEW 2012 (or compatible)

 

Steps to Implement or Execute Code

  1. Download the attached folder to your computer
  2. Open the VI " ROI Grid Overlay 2012 NIVerified.vi"
