Iterate through the composed RGB image with an image iterator. At each iteration, get the pixel of the boundary image. If it's a boundary pixel, set the pixel in the RGB image to red.<br><br><div class="gmail_quote">2011/5/15 LaMoOsH .. <span dir="ltr"><<a href="mailto:xlolla28x@hotmail.com">xlolla28x@hotmail.com</a>></span><br>

Hi, <br> <br>Thanks for you reply<br> <br>I did have a loot at them and they were helpful to get an idea about RGB images, but they were not helpful that much for my problem. <br>how can i make the detected bounadry in red for example ?<br>
Is there any type of iterator that iterate through the boundary?? since i dont have a first index and second index. <br> <br>Thanks <br><br> <br>

<br>LabelOverlayImageFilter may do what you want. I have not personally used it though. I usually use ComposeRGBImageFilter to create an RGB image from a scalar image then iterate the RGB image manually setting the color of select pixels.

<div>Hello, <br> <br>I have a grayscale image .. (CT scan image) and i already applied a level-set on that image to segment a region. <br>now, i want to add a colour on the segmented boundary. just as the manual segmentation with itk snap . <br>
the result that i have is the result of the shape detection level set and it is in black and white.. and i have the thresholder output too .. <br> <br>how can i draw the line of the boundary which is the result of the level set on my original grayscale image? <br>
<br>should i make two different outputs? so one is the output for the shape detection.. and another output of drawing the line on my original image? <br>should i convert the image into RGB? how can i assign a colour to each pixel in the bounday. <br>
<br>sorry for asking alot of questions , i am new to itk. <br>few hints on my questions will be very helpful and appreciated. <br> <br>Thank you :) <br> <br> <br></div><br>_____________________________________<br>Powered by <a href="http://www.kitware.com/" target="_blank">www.kitware.com</a><br>
