Feature matching on bigimage objects

Hello,

I would like to ask, how does feature matching on a bigimage object work? I am new in this field and I work a large GEOTIFF image, and I do not really know what is the syntax to detect, extract and match features on the blocks of the bigimage object. I would like to visualize the results too, but the imshowpair() function and showMatchedFeatures() function does not work because the reference image is a big image object. How can I visualize bigimage object?

I want to do something like the second example in this video, except that I want to use bigimage object as referencing:

I would be grateful if you could help me!
