Yes. It's a different kind of computer vision. Not the kind where you just throw an expensive NN at stuff and hope for the best, but one where we're actually dealing with operations at the pixel level (corner / edge features, image warping, stitching, calibration etc). No neural nets, just very fast operations on the actual image data.

It's useful either as a preprocessing step that you feed into further NN processing or -- super old school -- you are modeling your problem by hand instead of letting a NN figure it out (for better or worse).
