How to manually adjust after automated segmentation?

I am using the Image Segmenter App and I use the Graph Cut or another automated Segmentation feature. I then want to go back and manually fix it up. Is this possible?

>> coins = imread('coins.png');
>> imageSegmenter(coins)

Select Graph Cut, Mark Foreground and background and then Create Mask

Once the mask is created, all the Add to Mask tools (such as draw freehand) can be accessed to add to the foreground.

If you would like to change some of the foreground to become background, follow the steps below:

- Select the dropdown under Refine Mask and select Invert Mask

- Use an Add to Mask tool (such as draw freehand) to add to the background

- Invert the mask again
