9 Right image edge pixel band to ignore. 0..255 0 is default.

10 Top image edge pixel band to ignore. 0..255 0 is default.

11 Bottom image edge pixel band to ignore. 0..255 0 is default.

Use the “ignore edge pixel band” to indicate that the registration algorithm to not include these pixels

when determining the registration match. This can be used to compensate for effects of the optics such

as vignetting or when there is an obstruction along an edge of the image.

Set Video Parameters (0x10)

Set parameters used by tracking module. Default values: automatic detection of active video region

(auto-chop), apply deinterlacing. Sending this message resets registration and stabilization.

Many cameras produce images with black pixels along one or more edges. It is important to remove

these pixels as the hard edge transition can cause frame-to-frame registration to fail. The edge pixels

are removed by either setting automatic detection mode or manually specifying top, bottom, left and

right edge pixels to remove. For a known camera, manually specifying edge pixels is the most reliable

option. If you see black edges in a moving stabilized image, that is an indication that edge pixel

removal is not set up correctly.
