Yeah, it's conceptually pretty similar to that kind of stitching. In some ways stitching the DNA sequences together is less complicated than an image because the data are one-dimensional and you don't need to correct for perspective artifacts for near-field objects. On the other hand it's a crap-ton more data elements than the number of pixels in even an HD image, so overall it's a lot more data to crunch through. And there are different kinds of artifacts that show up in sequencing data (such as read errors or mutations that occur during the copying of the DNA prior to sequencing) that need to be dealt with.
