MATLAB: Editing a binary image mask based on original image

Question

I am running code that generates a binary mask based on an object in the image. When I overlay the boundary onto the raw image, I notice that while it is largely accurate, there are still some parts that are not correct. Is there a way where I can overlay the mask onto the raw image, similar to how image Segmenter does it, and then edit the mask? For example, erase some parts of it or add to the mask? Please let me know. Thank you!

You can use imoverlay() to superimpose your initial segmentation over the original image. Then outline or paint your corrections on that and convert it back to a binary image.
