How to merge two segmented parts of same Image???

I segmented ROI part of an image and applied some operation on ROI and Non-ROI separately. Now, after that, I want to merge these parts back to show the reconstructed image. How can I do this? Please provide a Matlab function to solve this problem. Thanks in advance...

Just OR them together:

finalBinaryImage = binaryImage1 | binaryImage2;

Thank Image Analyst for the response. For this, I converted the grayscale image segments into binary and getting result as a binary image. Now, how can I convert the resultant binary image into the grayscale image as I need the result as a grayscale image?

[Image Analyst]

Do you mean masking? Like

maskedImage = grayImage; % Initialize
maskedImage(~finalBinaryImage) = 0;  % Erase outside mask.

Thank you Image Analyst, I have used imfuse() to merge image.

can i know what is the grayImage here??

[Image Analyst]

That is the gray scale image that you want to mask. I called mine grayImage. What did you call your variable?

can you share the code on how to merge the two ROI images ?
