Image shows with imshowpair, but not with imshow

I am writing a function that reads an image and converts it to BW. I am able to use imshowpair to display the unedited and edited images next to each other, but can't individually show just the edited (BW) image. What should I do?

midAirImage = imread("MidAirTest.jpg");

bwImage = imbinarize(midAirImage,'adaptive','ForegroundPolarity','dark','Sensitivity',0.4);

imshowpair(midAirImage, bwImage, 'montage')

Your binary image should be 2 dimensional, if it is not convert the original image into gray cale and then create binary image,

midAirImage = imread("MidAirTest.jpg");

midAirImage = rgb2gray(midAirImage);

bwImage = imbinarize(midAirImage,'adaptive','ForegroundPolarity','dark','Sensitivity',0.4);

imshowpair(midAirImage, bwImage, 'montage')

imshow(bwImage);

You have two options, use subplots

subplot(121)
imagesc(midAirImage)
subplot(122)
imagesc( bwImage)

Alternatively you can concatenate your images like this

imagesc( [ midAirImage bwImage])

Notice that the binary will be between 0 and 1 and the original between 0 and 255 so you need to scale:

imagesc( [ midAirImage 255*bwImage])

Hope this helps to solve your problem.
