hi
have used edge detection to find the edge, i have had to threshold the image to find the edge, i also need to do further processing on image so try to save the untouched image using a buffer and imaq copy but what ever i do, the untouched image seems to have the edge detection search lines and results appear on that also. any body know whats going on here.
thanks jake

Hey Jake,
I made a little example here for you with a threshold instead of an edge detection. You basically need to do the imaq copy BEFORE you do the processing on the original image, or else the processed image will be copied. I hope this helps you some.

Hello Chris
I would like to know the step by step procedure for thresholding an image WITHOUT using IMAQ functions. How can it be implemented?
thnx

Nghtcrwlr,
We like to keep forums to a specific question or topic, that way others that may have insight can see what people are asking.
But basically, yes, you can. You will have to compare each pixel of an image to your desired threshold level, and if the pixel is greater, make it 0, if its less, make it 1. Or however you want to do it. It would just require nested for loops that are autoindexed for your pixels, and then compare each pixel.
There are probably other ways to do this, but this is the first I could think of.
