Can I remove the automatic color overlay in the Registration Estimator App?

Hello! I'm new to Matlab, and trying to register two dental images taken with an endoscope. My final registered image will be converted into a heatmap, so I need the registered image to be grayscale. If I were to apply a function like rgb2gray over the color overlay, then my heatmap would be innacurate. When I register my images using the Registration Estimator App, I'm not able to find a way to remove the overlay that is automatically added to my registered image. When I export the registered image to my workspace, I'm not sure how to view it, so I don't know if it has the color overlay added.

My images are attatched here. When using the app, I kept all of the default settings, but moved the 'Number of Detected Features' slider all the way to the right.

Thank you so much!

You can export the code and alter it however you wish. Click the Export button.

Hi! When I export to workspace and then select 'RegisteredImage' within the exported variable, I see a message that says 'Cannot display summaries of variables with more than 524288 elements.' Is there a way to view/save just the registered image after exporting? Thanks!

I haven't tried it yet. I'll need to do the same thing shortly and what I was planning on doing was exporting the code only, not the image, and integrating that exported function into my main code and then using imwrite to write the registered image to disk.

Exporting and then using imwrite worked for me, thank you so much for your help!
