How are the locations of points on the point cloud determined? Are they chosen specifically in locations with high variance?

The feature points can be determined automatically through some algorithms. Generally, we want points that must be prominent in both images, easy to localize -- one way that's easy is to simply detect corners, where two lines meet. We can find where corners are by using edge detection image algorithms. From there, we do feature matching.
