Abstract: Various techniques are disclosed herein, which comprise obtaining a first stream of images from a first camera and a second stream of images from a second camera, wherein the first camera and second camera have different poses, and at least a portion of the image streams are captured concurrently. Next, a first stabilized trajectory and corresponding set of corrections used to stabilize the first stream of images are calculated.

If desired, e.g., in response to determining that the stabilized first stream of images does not meet a stabilization criterion, the second stream of images may be stabilized using the second set of corrections.
