5 If you’re analyzing images for the first time, set the mode parameter to Precise.
If you’re not satisfied with the result later in the operation, change mode to Robust and
re-analyze the images.
6 Click the “analyze” button.
Shake steps through each frame in the image sequences and analyzes each set of
aligned images at every frame in the designated analysisRange.
Note: The analysis can be interrupted at any time by pressing Esc.
7 Once the analysis has concluded, set clipLayer to All in order to expand the Region of
Interest (ROI) to the overall width of the newly generated panorama.
8 Choose an input layer from the lockedPlate pop-up menu.
For purposes of creating a panorama, you should use an image that’s either already
stable, or one that has been locked down using the SmoothCam or Stabilize nodes.
Note: If the combined image is very wide, it may also be a good idea to set the
centermost image as the lockedPlate.
9 To output the entire panorama as a single image, set ouputFrame to All.
10 If the seams between each aligned image are visible, set the blendMode parameter to
smartBlend to make them invisible.
11 If the aligned images have different exposures, turn on matchIllum.
If you can still see differences in color or exposure, you can attach additional color
correction nodes between the upstream image and the AutoAlign node to make the
necessary adjustments.
Example 2: Aligning a Clean Plate Image With a Moving Shot
This example shows how to align a clean plate still image with an image sequence in
which the camera is moving.
To align a clean plate image with an overlapping image sequence:
1 Connect the clean plate image and the moving shot (in this example, the mountaineer
image) to an AutoAlign node.
