BgWarpFrames u8 Warp the background model if the above conditions are met for this

number of consecutive frames. 0 to 255, default 2. Allows for

ignoring a small number of bad frames or temporary large motion,

but warps when there is a significant amount of motion.

MaxTrackFrames u16 Number of frames to keep tracking once target has disappeared. 0

to 65535. 0 = automatic.

NEW 2.20 – Blend an EO (visible) and an IR camera. The EO camera can now be an HD digital

camera. The EO camera will always be the camera that “warps” into the space of the IR camera to

produce the output image.

When both cameras are standard definition with similar fields of view, set Absolute Zoom Mode off to

scale the EO camera to match the IR. When the EO camera is HD, Absolute Zoom Mode can be turned

on to achieve a more significant zoom factors. For example, if a 1280x720 HD camera is to be blended

with a 640x480 camera where the horizontal fields of view match, pass zoom=128 and zoom absolute

= 1 to get a zoom factor of 0.5 which will scale the HD image to 640x360 before blending.
